The document discusses four reasons why people should wait on God: 1) God is faithful as shown in Isaiah 30:18 and Psalm 27:13-14. 2) People make hasty decisions when they don't wait. 3) God is preparing them for what's ahead as Psalm 40:1-4 illustrates. 4) God's timing is different than humans' as Psalm 31:14-15 notes that one's times are in God's hands. To avoid the mistake of not waiting on God, the document recommends trusting God, listening, remembering past examples, and praying.
