For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one Man the many will be made righteous (Romans 5:19).
The world in which Adam and Eve lived would have been perfect in every way—weather, temperature, lush fruits, incredible surroundings, nothing to diminish their enjoyment of knowing God in a most intimate way. And God had companionship directly with them. When the cool evening breezes were blowing, the man and his wife heard the Lord God walking about in the garden.
Of course, we know that didn’t end well. When sin entered the world, our holy God could not be in the presence of sin.
All our sins from merely embellishing the truth to inflicting horrific torture can be traced back to our inheritance of this sinful nature. Left to our own devises unconstrained, we fall back into greed, envy, selfishness, pride, gluttony… All the sins we commit are a manifestation of this sinful nature.
But God had a redeeming plan from the start to restore His cherished fellowship with mankind for those who so choose. When Jesus suffered as our substitute He was sinless, but He assumed our sinful nature long enough to defeat it. He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him.
This is so well explained in the words of this song:
“I am covered over with the robe of righteousness that Jesus gives to me.
When [God] looks at me He sees not what I use to be, but He sees Jesus.”
We can have fellowship with God now in the spirit, and can look forward to someday walking with Him in the cool evening breezes.
