We have been born and inherited the consequences of sin since the time of Adam and Eve, sin entered the world through man and through a man the sin of the world is also taken away.
Jesus was born of a virgin woman, during his life he did not practice sin, he was totally God and totally human, Jesus was perfect and had the same weaknesses as us, he suffered the same ailments as us.
Jesus was the man who by his sacrifice took away the sin of the world, that is, everyone who believes that Jesus died and rose again to redeem us, is a son of God and has passed from death to life. The death of Jesus was to free us from the condemnation of sin, from the disease of sin.
Who himself bore our sins in his body on the tree, that we, being dead to sins, might live to righteousness; and by his stripes you were healed
1 Peter 2:24
