Can “religion” save me from death in Hell?

No, “religion” (theologically speaking) is defined as a theological process by which a man or woman earns their way into relationship with a specific deity…religion is “works based” suggesting that mankind can work sufficiently or do something sufficiently pleasing, be sufficiently “good” to earn favor with God.

Christianity is “faith based” meaning that the Holy Bible/the Holy Spirit teaches that all of humanity is under the penalty of sin (Romans 3:23; 5:12), there is NOTHING we can do in and of ourselves to earn God’s forgiveness/acceptance but that Jesus, in HIS divine perfection, paid the required price for our sin on the Cross at Golgotha (1 Peter 1:18-19) and the Father declares that anyone who trusts in what Jesus has done for them will be declared “not guilty” (John 3:16; Hebrews 8:12) based solely on the work of Jesus on our behalf (Romans 4:4-5).

Man is not saved from sin and Hell by works or deeds or behavior but man is saved and enters into covenant relationship with Elohim by faith in the ONE, Jesus Christ, who did the work for us; therefore, the answer to your question is not “religion” but “Christianity” (Galatians 2:16).
