Bible Verses About The Second Coming of Christ: Is not to make atonement

For we know that since Christ was raised from the dead, He cannot die again; death no longer has dominion over Him.

The death He died, He died to sin once for all; but the life He lives, He lives to God.

so also Christ was offered once to bear the sins of many; and He will appear a second time, not to bear sin, but to bring salvation to those who eagerly await Him.

because by a single offering He has made perfect for all time those who are being sanctified.
