Keep a song in your heart.
God's timing is perfect. It's in the Bible, Romans 5:6, TLB. "When we were utterly helpless, with no way of escape, Christ came at just the right time and died for us sinners who had no use for Him."
God's timing is controlled by his compassion. It's in the Bible, II Peter 3:8-9, TLB. "But don't forget this, dear friends, that a day or a thousand years from now is like tomorrow to the Lord. He isn't really being slow about his promised return, even though it sometimes seems that way. But He is waiting, for the good reason that He is not willing that any should perish, and He is giving more time for sinners to repent."
There is a time for everything under the sun. It's in the Bible, Ecclesiastes 3:1-8, NIV. "There is a time for everything, and a season for every activity under heaven: a time to be born and a time to die, a time to plant and a time to uproot, a time to kill and a time to heal, a time to tear down and a time to build, a time to weep and a time to laugh, a time to mourn and a time to dance, a time to scatter stones and a time to gather them, a time to embrace and a time to refrain, a time to search and a time to give up, a time to keep and a time to throw away, a time to tear and a time to mend, a time to be silent and a time to speak, a time to love and a time to hate, a time for war and a time for peace."
