Hebrews 11: 6, says: “Without faith (trust) it is impossible to please God, because anyone who comes to Him must believe (trust) that He exists and that He rewards those who earnestly seek him.” This is about the attitude of trust in God. You just don’t have a chance with God unless you trust Him. Since you can’t see Him, you must trust that He exists. (Funniest thing though, when you start trusting Him, you start seeing the things He does, and feeling His Presence all around. He reveals Himself to you.) And you must trust that He’ll reward you if you earnestly seek Him. Like it says in James 4:8, “Draw near to God, and He’ll draw near to you.” ‘Drawing near’ could be translated, ‘earnestly seek Him’.
Further down in Hebrews 11, it talks about the great men and women of faith in the Old Testament. Like Abraham, Moses, Elijah, Noah, Isaac, Jacob and Joseph; “And what more shall I say? I do not have time to tell about Gideon, Barak, Samson, Jephthah, David, Samuel and the prophets, who through faith (trust) conquered kingdoms, administered justice, and gained what was promised; who shut the mouths of lions, quenched the fury of the flames, and escaped the edge of the sword; whose weakness was turned to strength; who became powerful in battle and routed foreign armies. Women received back their dead, raised to life again.”
All these people trusted that God exists and that He rewards those who earnestly seek Him. They experienced God’s rewards. These people exhibited the attitude that God likes, the attitude that makes Him happy, and that attitude is TRUST. When we exhibit it, it makes us happy too! (No matter what circumstances we may find ourselves in.)
