I once heard someone making the case that David’s faith, as he went to fight Goliath, was really not quite as extraordinary as it might initially appear. “You see,” the argument went, “God told David what was going to happen. David already knew that he would be able to defeat Goliath.” From a human reasoning standpoint, I can understand how any foreknowledge David may have had could make the story less impressive.
If he already knew what would happen, then was he really all that brave? Did it really take that much faith if God had already tipped David off about what was going to happen?
In reality, however, this is not a good argument against the strength of David’s faith. It is actually closer to the definition of faith. In fact, having God tell us things is where faith comes from in the first place.
“So then faith comes by hearing, and hearing by the word of God.” (Rom 10:17 NKJV) In Genesis 15 God told an elderly, childless man that he would have offspring that would be as numerous as the stars. In verse 6 we are told that when Abraham (at that point still Abram) heard God tell him these things that he actually “believed God.” Hebrews 11:11 says that the way Abraham was able to become a father was by faith. Abraham “considered him faithful who had made the promise.” “By faith Abraham, even though he was past age—and Sarah herself was barren—was enabled to become a father because he considered him faithful who had made the promise.” (Heb 11:11 NIV) Let’s hear what God has to say about us, stand on His promises & claim by faith what God has provided by grace!
“He who calls you is faithful, who also will do it.” (1 Thess 5:24)
