"For if by one man's offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ." (Romans 5: 17)
What Adam's sin did to mankind, Jesus overcame through His death and resurrection.
"14Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; 15And deliver them who through fear of death were all their lifetime subject to bondage. (Hebrews 2: 14-15)
Jesus became sin, that we might become the righteousness of God in Him (2 Corinthians 5: 21), a gift which we keep on receiving.
The grace of God now works within us, just as it propelled Paul:
"But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me." (1 Corinthians 15: 10)
"Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;" (2 Corinthians 3: 5)
Through Jesus, we have gone from dead in our trespasses (Ephesians 2: 1) to alive and seated in heavenly places (Ephesians 2: 4-6).
He even causes us to be kings and priests:
"9But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: 10Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy." (1 Peter 2: 9-10)
Today, let us rest in the growing revelation of God's blessed, gracious goodness. Jesus did not just die on the Cross to pay for our sins, and indeed He paid for all of them (Colossians 2: 13). Through Jesus' death and resurrection, we receive a spirit of sonship (Romans 8: 15) in which we can come boldly to the throne of His grace (Hebrews 4: 16).
