Romans 5:15

Romans 5:15 But the gift is not like the trespass. For if the many died by the trespass of the one man, how much more did God’s grace and the gift that came by the grace of the one man, Jesus Christ, overflow to the many!

The whole human race died by the sin of one man, Adam.  The gift of God’s grace came by the one man, Jesus Christ.  This grace has brought spiritual life to many.  Therefore, by grace alone through faith alone in Christ alone the many will receive the gift of eternal life by being in Christ by spiritual birth rather than being in Adam by physical birth.  Instead of being children of Adam and represented by him, Christians are represented by Christ and are children of God.  Praise God that we can reverse the effect of Adam’s original sin by faith in Christ.  By the grace of God we can regain the paradise that was lost by our first representative Adam.
