Verses 11-14 of the 13th chapter of Romans:
Besides this you know what hour it is, how it is full time now for you to wake from sleep. For salvation is nearer to us now than when we first believed; the night is far gone, the day is at hand. Let us then cast off the works of darkness and put on the armor of light; let us conduct ourselves becomingly as in the day, not in reveling and drunkenness, not in debauchery and licentiousness, not in quarreling and jealousy. But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.
