What does the Bible say about encouraging oneself in God?

In 1 Samuel 30:6-8, we see David, greatly distressed by the loss of his city and the threats from his own men, encourage himself in the Lord his God. This act of encouragement is a powerful example for believers, demonstrating that in times of trouble, turning to God in prayer and faith can provide both comfort and guidance. David sought God's direction after encouraging himself, showing that true encouragement comes from trusting in God's faithfulness and sovereignty. Encouraging oneself in the Lord means recognizing His past faithfulness and relying on His promises amidst current trials.
