The question is asked in the book of 1 John. How are we to become overcomers? Jesus answers by saying that you must believe with all your heart that I am the Son of the living God.
Paul tells us more about being overcomers. He says that Jesus, the Lord, knew no sin. was made sin in our behalf. This He willing did that we who are nothing but sin might become righteous, without sin, by depending upon Him to give us the power we need to do so.
Then we will be able to sing
My Savior forever.
