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 (KJV)
Righteousness is a gift we receive, not a reward we work for. When we receive this unspeakable gift through our faith in the finished works of Jesus, we enter into the abundance of God’s grace—His unmerited favor. His grace being abundant means it is sufficient to wipe out all of our past mistakes, and to supply us with everything that is needed in order for us to live a successful and overcoming life.
