Christ was offered once to bear the sins of many;
and he will appear the second time,
not to bear sin,
but to bring full salvation to those who are waiting for and expecting Him.
Heb 9:28

When he appears, we will be like him,
for we will see him as he is.
And every man who has this hope in him
purifies himself, even as he [Jesus] is pure.
1 John 3:2-3
And now, little children, abide in him,
so that when he appears, we may have confidence
and not be ashamed before him at his coming.
1 John 2:28
