Without the Death of Jesus Christ on the Cross, we are not Christians. A Christian believes in the death and resurrection of Christ.
Without the Cross, we are not free; we have no eternal salvation (No access to Heaven or God); our sins are not forgiven; we are not victorious; and we are not overcomers.
Revelation 12:11
“And they overcame him (SATAN) by the blood of the Lamb (JESUS) and by the word of their (OUR) testimony, and they (US) did not love their (OUR) lives to the death.”
