1 Corinthians 11:19

19 For there must also be factions among you, so that those who are approved may become evident among you.

25 For He must reign until He has put all His enemies under His feet.

1 Corinthians 15:53

53 For this perishable must put on the imperishable, and this mortal must put on immortality.
