2 Peter 3:9 

We have to learn to work on His time, not our time. For there might be a bigger meaning in waiting for a prayer to answer. But He will never forget you.

The Lord isn’t really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent.
2 Peter 3:9 NLT
