Doh!! what I meant to say is this: redemption is NOT salvation, Salvation requires obedience to the Ten Commandments
Romans 10:9 King James Version (KJV) 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Ephesians 2:8-9 King James Version (KJV) 8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast.
If you could save yourself by following the law then Jesus wouldn't have needed to die for our sins and our salvation would depend on our works, which are like filthy rags in the sight of God. As a believer what if I sinned and died before I could ask for forgiveness?
If there was a way to lose your salvation, we all would lose it. Our salvation is dependant on God's grace. There are those who may pray a prayer but never truly repent in their hearts, but they weren't saved to begin with. Once we are truly saved we are sealed with The Holy Spirit, who gives us the desire to follow God's commandments.
