Ephesians 1: 4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love. having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will.
Therefore, according to what is written in the Bible we can decisively conclude that the plan of salvation was not a reaction to some emerging threat but was a well thought out plan made well in advance, to be implemented when it would become necessary. We use the word “When” because as the Scripture says unequivocally, God reads the future accurately, and therefore it was not a matter of if, but a matter of when man would fall.
[D.A. pp 22] The plan for our redemption was not an afterthought, a plan formulated after the fall of Adam. It was a revelation of “the mystery which hath been kept in silence through times eternal.” From the beginning, God and Christ knew of the apostasy of Satan, and of the fall of man through the deceptive power of the apostate. God did not ordain that sin should exist, but He foresaw its existence, and made provision to meet the terrible emergency.
So great was His love for the world, that He covenanted to give His only-begotten Son, “that whosoever believeth in Him should not perish, but have everlasting life.” Lucifer had said, “I will exalt my throne above the stars of God; ... I will be like the Most High.” Isaiah 14:13, 14. But Christ, “being in the form of God, counted it not a thing to be grasped to be on an equality with God, but emptied Himself, taking the form of a servant, being made in the likeness of men.”
Isaiah 46: 9 Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me, 10 Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure.
May The Lord add His blessing to the study of His word. God bless!
