1 Corinthians 15:17- And if Christ has not been raised, your faith is futile; you are still in your sins.
The passage declares if Christ is not risen, raised from the dead, resurrected then our faith is in vain and we are still dead in our sins. We are saved by His life/Resurrection not His death. His death atoned for sin but does not give life.
Romans 4:24-25
but also for us, to whom God will credit righteousness—for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification.
Paul declares in Romans 5:10 the following: For if, while we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! Cf Acts 17:31.
John 11:25-26
Jesus said to her, “I am the resurrection and the life. The one who believes in me will live, even though they die; 26 and whoever lives by believing in me will never die. Do you believe this?”
