In RomansΒ 5:12Β God tells us how we are all related to the first man, Adam:
βWherefore, as by one man sin entered into the world, and death by sinβ¦ so death passed upon all menβ¦β
This verse clearly indicates that every child born into the world since Adam has partaken of Adamβs sinful nature.
Parents sometimes wonder why their children act as they do. The answer is simple! Every child is related to rebellious Adam by physical birth, and soon rebels like Adam, whose offspring he is.
In Scripture we are told that God βcommendeth His love toward us, in that, while we were yet sinners, Christ died for usβ (Rom. 5:8).
When you are in trouble and someone comes to your aid, are you not automatically drawn to that person? Should we not then be attracted to the One who cared so much for us that He βmade Himself of no reputation, and took upon Him the form of a servant, and was made in the likeness of men: and being found in fashion as a man, He humbled Himself, and became obedient unto death, even the death of the crossβ (Phil. 2:7,8)?
Through natural birth we partake of the sinful natures of our parents back to Adam, and frequently we even have the same physical features as our parents. How touching, then, to know that the Lord Jesus Christ took on Him βthe likeness of menβ (apart from sin) and, as the God-man, died for our sins upon the cross, where sinful men (people like us) nailed Him! As we recognize this and place our faith in Him, a spiritual birth takes place and we become the children of God (John 1:12). More than this, we become members of the Body of Christ, Godβs new creation, for βif any man be in Christ, he is a new creationβ (II Cor. 5:17) βcreated in Christ Jesus unto good works, which God hath before ordained, that we should walk in themβ (Eph. 2:10). source
