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)

Notice that there is an abundance of grace. In other words, there is no such thing as a grace shortage. This means no matter what our past may have looked like, we have been made the righteousness of God in Christ Jesus as a result of what Jesus has done for us. Now God’s super-abounding grace is sufficient to meet every need in our lives.
