God’s word wasn’t enough for the Israelites. The Lord had given them incredible promises, yet in the midst of their crises, Israel never trusted Him. In spite of every promise, they rendered His word useless. How? By never mixing it with faith. “The word preached did not profit them, not being mixed with faith in them that heard it” (Hebrews 4:2).

Instead, the people always demanded a new word from God. In other words: “We need to know whether God is with us in this present crisis, not just our last one. We must have a new revelation from Him for this situation.” I ask you, how could anyone forget so quickly all that God had done for them? Israel had forgotten every instance of God’s deliverance and had not allowed His past supernatural works to build up their faith in Him.

Yet, in spite of their accusations against Him, God spoke another word to Israel. He instructed Moses to tell them, “Dread not, neither be afraid of [your enemies]. The Lord your God which goeth before you, he shall fight for you, according to all that he did for you in Egypt before your eyes” (Deuteronomy 1:29-30).

Now, this wasn’t a new promise. God was simply restating what He had already told His people: “The Lord shall fight for you, and ye shall hold your peace” (Exodus 14:14).

Over and over God had told them, “I am with you. I’m going to fight for you so lay hold of this promise and don’t forget it.” Yet, here they were, trembling before their enemies and focusing on their own weakness. Finally, they reasoned, “We’re not able to go up against them.” This was blatant doubt—doubt of God’s call on their lives, doubt that He had sent them, doubt of His presence in their midst.

You may think you would never react this way, yet so many Christians today say similar things: “Lord, are You really with me? I know what You promised me, but is it really true? Can I trust what You’ve said? I need a fresh word. Please, give me some more assurance.”

We end up trembling before the enemy of our souls and it is all because we don’t believe what God has promised us. We act as if He has never said a word to us and we begin to “tempt” Him. Even though He has proven Himself to us again and again, we continually ask Him to prove His faithfulness anew, to send us yet another faith-building word. But God will speak only one word: “Believe what I have said to you. Trust Me.”
