For if when we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.
Romans 5:10 NKJV
we where once gods enemies but he made us his friends through the death of his son on the cross and now that we are gods friends much more will we be saved by christ
For since our friendship with God was restored by the death of his Son while we were still his enemies, we will certainly be saved through the life of his Son. Imagine how much more good would come out of life in his son.
