For it is by grace that you are saved through faith and not of your own works. It is a gift of God lest anyone should boast.(Ephesians 2:8)
The free gift of God is eternal life. Salvation and our security in God requires no effort on our side. God has already done everything all we need to do is receive it. Faith is the hand that receives the grace of God. We do not have to clean up, we do not have to be perfect -just receive the gift of God!
