Ephesians 4:29-32
Never let evil talk pass your lips; say only the good things men need to hear, things that will really help them. Do nothing that will sadden the Holy Spirit with whom you were sealed against the day of redemption. Get rid of all bitterness, all passion and anger, harsh words, slander, and malice of every kind. In place of these, be kind to one another, compassionate, and mutually forgiving, just as God has forgiven you in Christ.
Romans 13:11-12
It is now the hour for you to wake from sleep, for our salvation is closer than when we first accepted the faith. The night is far spent; the day is near. Let us cast off the deeds of darkness and put on the armor of light.
