From the OP: View of the substitution of atonement.
Would you buy/agree?
God created a being, the devil, who had the power of the death.
And that's what the devil, did, would do and is still doing. Therefore because of the devil having the power of, the death, God, before the foundation of the world, determined to:
Substitute himself as one subject to, the death, in order to destroy the devil and his works including, the death. 1 John 3:8 & Heb 2:14
How to do this? How about create a man, subject to, the death, give the man, a law, the power of the sin 1 Cor 15:56, sold under sin, take woman from the man, then send the Word born of the woman taken from the man as the Son of God subject to the power of death, having faith that sinless Son would give his sinless life (die the death of Gen 2:17) a ransom for that sold.
After three days and three nights give life again unto the Son raising him out of the dead (Sheol/Hades, incorruptible) thus setting the example for the destruction of the devil his works including the death. 2 Tim 1:10 and was made manifest now through the manifestation of our Saviour Jesus Christ, who indeed did abolish death, and did enlighten life and immortality through the good news, Romans 16:20 and the God of the peace shall bruise the Adversary under your feet (in quickness) quickly; the grace of our Lord Jesus Christ be with you. Amen! 1 Cor 15:52-55 in a moment, in the twinkling of an eye, in the last trumpet, for it shall sound, and the dead shall be raised incorruptible, and we -- we shall be changed: for it behoveth this corruptible to put on incorruption, and this mortal to put on immortality; and when this corruptible may have put on incorruption, and this mortal may have put on immortality, then shall be brought to pass the word that hath been written, 'The Death was swallowed up -- to victory; where, O Death, thy sting? where, O Hades, thy victory?'
Gen 22:8 And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.
