So many things that are absolutely vital for the believer are attached to the fact of the resurrection of the Messiah Jesus. The Scriptures clearly show how significant the resurrection really is.
It’s necessary to believe in the resurrection in order to be saved
If a person does not believe in the literal, bodily resurrection of the Messiah Jesus, they cannot be saved no matter what they think or say. The resurrection is a cardinal doctrine that must be part of one’s belief system.
Rom 10:9-10 - that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
