“In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.”
Ephesians 1:13-14 ESV
As Christians, we believe that Our Lord and Savior Jesus Christ died to make us right with God. He took on the sins of all who believe in Him, once and for all. I have read various views of whether salvation can be lost, once it has been received by faith. Obviously, we do not receive it by our works and many, including Billy Graham, believe that we don’t lose it because we continue to sin. As an oncologist who encounters deaths regularly, I pray that saved souls cannot be lost.
