First of all, a few statements pertaining to God himself, that he is a God who does not change, that that which he is purposing: he also will establish.

Jas. 1:17  “Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.”

Mal. 3:6  declares: “For I am the LORD, I change not.”

Indeed, therefore, when God purposes something, it will surely come to pass, no matter in what way any human being, or even the Devil, tries to interfere with it. God himself is giving us this assurance:

Is. 55:8–11  “For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts. For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater: so shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.”

Is. 14:26–27  “This is the purpose that is purposed upon the whole earth: and this is the hand that is stretched out upon all the nations. For the LORD of hosts hath purposed, and who shall disannul it? and his hand is stretched out, and who shall turn it back?”

Already the great prophet Moses declared:

Num. 23:19  “God is not a man … that he should repent [the wise of the human race should ever keep this in their minds, but do they?]: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?”

Therefore, then, God purposed and declared:

Gen. 22:16–18  “By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son [God accepted Abraham’s proceedings as an accomplished deed], thine only son [which typified God’s act of giving his only begotten Son to be sacrificed in actuality]: that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed [Gen. 12:3 says: “and in thee shall all families of the earth be blessed”]; because thou hast obeyed my voice.” (Also Gen. 18:18; 26:4; 28:4; Gal. 3:8).

To this, the Apostle Paul adds this declaration:

Gal. 3:16  “Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.”

Expressing the same purpose of God — that all nations, all families of the earth shall be blessed in due time, the Apostle Paul declares that it is God’s express will to:

1 Tim. 2:4  “… have all men [all people] to be saved.”

To establish this (God’s purpose regarding the human race, viz, regarding Adam and all his posterity), we are being told that:

1 John 4:14  “The Father sent the Son to be the Saviour of the world” (to be the Executor of all the aspects of God’s purposed Plan of Salvation for Adam and all his posterity).

Again, the Apostle Paul confirms this in these words:

Acts 13:47  “I have set thee [Christ] to be a light of the Gentiles, that thou shouldest be for salvation unto the ends of the earth.”

Jesus also said:

John 12:47  “And if any man [any person] hear my words, and believe not, I judge him not: for I came not to judge the world [during the Gospel age], but to save the world [in due time; according to God’s time-table, according to God’s “times and seasons”].”

This is also corroborated in these words:

John 3:17  “For God sent not his Son into the world to condemn the world [during the Gospel age]; but that the world through him might be saved [in due time, as explained a little later].”

The saving of the world is explained further in these Scriptures:

Rom. 5:12  “Wherefore, as by one man [Adam] sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.”

Rom. 5:18  “Therefore as by the offense of one [Adam] judgment came upon all men to condemnation; even so by the righteousness of one [the man Christ Jesus] the free gift came upon all men [shall come in due time] unto justification of life.”

1 Cor. 15:21–22  “For since by man [Adam] came death, by man [the man Christ Jesus] came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive [in God’s due time].”

It is for this reason and in this context that Jesus said:

Matth. 18:11; Luke 19:10  “For the Son of man is come to save that which was lost.”

What was lost? What did he come to save? Well, of course, Adam lost his life, he lost his perfection, he lost his Creator’s favour, he lost everything the moment God pronounced his sentence: “For in the day that thou eatest thereof dying thou shalt die” (see margin of Gen. 2:17). Dying thou shalt die means, of course: a decaying process which was to affect Adam and all his posterity: physically, mentally, as well as morally. Also, since “one day is with the LORD as a thousand years, and a thousand years as one day” (2 Pet. 3:8; Ps. 90:4), Adam did begin to die at his condemnation for his disobedience, and his life ended completely when he was 930 years old, before the 1000-year “day” ended. It is all that which was lost by Adam’s disobedience to his Creator’s law, which the man Christ Jesus came to save, by buying it back by his sacrificial death, for which reason we also read:

John 1:29  “Behold the Lamb of God, which taketh away the sin of the world.”

It should be noted how specific this Scripture is: it uses “sin” in singular — namely, Adam’s sin which, by extension, is the sin of the world. This is exactly the Apostle’s reasoning and explanation in Rom. 5:12,18, and 21, as already mentioned. It is also in harmony with all this that we read that the man Christ Jesus:

Heb. 2:9  “… by the grace of God [in his plans and purposes; as a designed feature of his Plan of Salvation for Adam and all his posterity] should taste death for every man”, and thus:

1 Tim. 2:6  “… gave himself a ransom for all.”

The word “ransom” means: a corresponding price, a price that corresponds exactly to that object to which it is applied, for the purpose of buying it back, which in this case is: a perfect human life. In harmony with this we read also:

1 John 2:2  “And he is the propitiation for our sins [viz, the satisfaction for our sins, as first applicable to the true Church of Christ; then the Apostle continues] … but also for the sins of the whole world [the hereditary sins, as a consequence of Adam’s imperfection].”

All of these reasons and specifics are incorporated in the few words of one of the Gospel’s main pronouncements:

Luke 2:10–11  “And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour [a life-giver], which is Christ the Lord.”

And when is all this applicable, as far as the whole world is concerned, as far as Adam and all his posterity is concerned? The Apostle Peter tells us:

Acts 3:19–21  “Repent ye therefore, and be converted [the Diaglott translation, direct from the Greek to English, reads: “Reform, therefore, and turn”], that your sins may be blotted out, [When?] when the times of refreshing shall come from the presence of the Lord [after his second Advent]; and he [God] shall send Jesus Christ [the glorified Jesus Christ at his second Advent], which before was preached unto you [throughout the Gospel age]: whom the heaven must receive [up from the time of his resurrection] until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began [in types, pictures, parables, and, yes, even directly].”

It is then (at the beginning of “the times of restitution of all things”), when our Lord’s words become applicable:

John 5:28–29  “Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice [not literally, of course], and shall come forth; they that have done good, unto the resurrection of life [viz, those who already have God’s approval up to “the times of restitution of all things”]; and they that have done evil [all the rest of mankind], unto the resurrection of judgment.”

The word “damnation”, as is usually found at the end of this verse, is incorrect; it is judgment, a judgment which will take in the time period of God’s true Kingdom, when the “King of kings and Lord of lords” reigns, which is the same period designated as “the times of restitution of all things”, when our Lord’s words will become true:

Matth. 6:10  “Thy kingdom come. Thy will be done in earth, as it is in heaven.”

It is then indeed:

Is. 26:9  “When thy judgments are [indeed] in the earth, the inhabitants of the world [Adam and all his posterity] will learn righteousness.”

Because it is then, that he, God:

Acts 17:31  “… hath appointed a day [the day], in the which he will judge the world in righteousness by that man whom he hath ordained [and who was “highly exalted” and “glorified”, because he “gave himself a ransom for all”]; whereof he [God] hath given assurance unto all men, in that he hath [then, and because of it] raised him from the dead.”

It is then:

John 3:15–16  “That whosoever believeth in him [in the reigning Christ during “the times of restitution of all things”] should not perish, but have eternal life. For God so loved the world [knowing the end from the beginning and thus looking forward to the completion of His Plan of Salvation for Adam and all his posterity], that he gave his only begotten Son, that whosoever believeth in him [then, during “the times of restitution of all things”; then, in God’s true Kingdom] should not perish, but have everlasting life.”

It is then also, that a number of other things develop and become a reality, for instance:

Rev. 21:4–5  “And God shall wipe away all tears from their eyes [not literally, of course]; and there shall be no more death [Adamic death], neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. And he that sat upon the throne said, Behold, I make all things new.”

And imagine these glorious conditions:

Is. 11:6–9  “The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them. And the cow and the bear shall feed; their young ones shall lie down together: and the lion shall eat straw like the ox. And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice’ den. They shall not hurt nor destroy in all my holy mountain [in all my holy Kingdom]: for the earth shall be full of the knowledge of the LORD, as the waters cover the sea.”

No one will be able to claim ignorance; all people of the earth shall then be made to understand all of God’s dealings with man: the permission of sin and, as a consequence, the experience with the results of sin; that Adam and all his posterity had to have these experiences until, according to God’s measure, the earth will have reached its fill with human population, involving more than 6000 years; and that then, by comparison, they will have the experience of “the times of restitution of all things”.

There are many more Scriptures like this, all describing the glorious conditions and developments during that age to come which will lead all the people of mankind to declare, by and by:

Is. 25:9  “And it shall be said in that day, Lo, this is our God; we have waited for him [unconsciously, in the far corner of our heart, we have hoped for such a God], and he will save us: this is the LORD; we have waited for him, we will be glad and rejoice in his salvation.”

But then will also be the time:

Phil. 2:10–11  “That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.”
