2 Peter 3:8-9 (NIV)
But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance.

Habakkuk 2:3 (NIV)
For the revelation awaits an appointed time; it speaks of the end and will not prove false. Though it linger, wait for it; it will certainly come and will not delay.

Psalm 31:14-15 (NIV)
But I trust in you, Lord; I say, “You are my God.” My times are in your hands; deliver me from the hands of my enemies, from those who pursue me.
