This is a matter that might be stated in different terms and yet stated correctly. We might say that we have universal redemption, in that the redemption is on behalf of all, and that the results of the death of Christ will be made efficacious to all of Adam’s race.
Are you describing "universalism" whereby all humans will be saved by the fact that Christ died for all?
When it is made efficacious to all it will mean their salvation—either that they will be actually and fully saved out of sin and death conditions, or that they will have a full, complete opportunity for recovery out of sin and death, with only their wills to intervene.
The Bible clearly teaches that man's ONLY requirement for salvation is to RECEIVE the free gift on the basis of faith. That is not a matter of man's will, but of man's reception of an offered gift.
An everlasting salvation, a complete deliverance from sin and death, will require the individual’s full co-operation.
"full co-operation" can mean many things to many people. So, to be clear, the ONLY response by man to the offer of salvation, is to believe the offer.
There is a Law of God which when broken leads to a sentence of death, as in the case of Father Adam. Broken by any one who has been delivered from the sentence of Adam and fully restored, that Law would mean that individual’s condemnation to death afresh.
So you believe that a saved person can ultimately be lost??? The Bible does not teach this.
The Bible speaks of this condemnation as the Second Death, which it teaches some will undergo.
In fact, all human beings are appointed ONCE to die (physically) and then the resurrection.
Acts 24:15 and John 5:28,29 clearly indicate that both believers and unbelievers will be resurrected. However, believers will receive glorified immortal bodies while unbelievers simply get their mortal bodies back, in order to attend the GWT judgment.
According to Rev 20:15, all unbelievers will be cast into the lake of fire. This will be a SECOND DEATH of their mortal physical bodies. That's why the LoF is called the "second death". It refers to a second physical death.
All humans are born spiritually dead. So their souls/spirits cannot die again. Unless a person is born again, and therefore made spiritually alive, they remain spiritually dead. Once born again, they CANNOT DIE spiritually again.
Adam was on trial for this life eternal, but he failed at the outstart of his trial.
The Bible does not say that Adam was "on trial". He was given only 1 command of what not to eat, and the consequences if he did eat.
Yes, he did fail to obey that command and suffered the consequences.
The world of mankind at the opening of the Millennium will start in a different way. They will start imperfect; but, with an experience in the nature and effect of win, and under the covering of Christ’s work—not granted as an individual imputation, but through the operation of the Mediatorial Reign—they will be permitted to rise up, up, up, out of sin and death; and while having this privilege they will be permitted to demonstrate their real character, whether determined for good or for evil. If they faithfully determine for good, they will gain eternal life; if for evil; they will lose eternal life, and will die again and be dead forever—incur the Second Death.
This seems rather fanciful, since there is nothing in the Bible about such opportunities for mortals during the Millennium. In fact, we know that since all believers will receive their glorified immortal bodies "when He comes" at the Second Advent, the ONLY mortals left to enter the Millennium will be the unbelievers who survive the Tribulation.
And what is clear is that at the end of the Millennium, there will be a global rebellion against "God's people" and all nations will gather to attack them, called the battle of Gog and Magog. All of them will be destroyed by God, and then resurrected to attend the GWT judgment.
