“In God we trust” may be a familiar idiom, but what does it look like when the rubber meets the road? Let’s take a look at a biblical example of what it means to trust in God in a practical sense. In Psalm 56, David gives some substance to the nature of trust.
Running for Your Life
Look first at the extraordinary situation from which David pens these words. The introduction of this Psalm says that it is written when the Philistines seize David in Gath. Here’s the backstory: David is a young man whom God has anointed to become the next king of Israel (1 Samuel 16:1, 12 13); the current king, Saul, is obviously not in favor of this, so Saul turns against David (1 Samuel 18:10ff) and sets out to kill him (1 Samuel 19:1).
David is therefore running for his life and unfortunately ends up in the hands of his greatest enemy, the Philistines—carrying their slain hero’s sword, no less (1 Samuel 21:9–10). This is clearly not a good situation for David. The people of Gath immediately recognize David and, with a mixture of cowardice and cunning, David feigns madness to escape the deadly situation (vv. 12–15).
David writes Psalm 56 in the midst of this terrifying situation. In it, David admits that when faced with a dire circumstance his initial reaction is marked by fear and panic. However, more important than his gut reaction, David asserts that steadfast trust in the Lord is the only solution to a troubling scenario like this. Easy to say, but what does that kind of trust actually look like?
In order for us to understand the testing that David’s faith is undergoing, a large portion of Psalm 56 is spent cataloging how his enemies are bent on destroying him: vv. 1, 2, 5, and 6 all detail the unceasing assaults from which David is running. He is trampled, oppressed, attacked, and his cause is injured. He is the subject of evil thoughts and is the target of a strife-inducing manhunt that is ultimately aimed at ending his very life.
Trembling and Believing
In the middle of this catalog of doom, verse 3 shows us that David is no Stoic—he openly admits fear. But the great thing about this honest confession is that he immediately follows it up with an affirmation of his trust in God. It’s important to see from this that, in some sense, it is possible for fear and faith to occupy the same mind at the same moment.
So that’s what David was up against, but what does his assertion of trust amount to? David tells us three times in vv. 4 and 10 that he puts his trust in God, “whose word I praise.” To trust in God is to rightly value His word. David trusted God by believing that God would actually do what He had promised to do. Specifically for David, the word he trusted was likely God’s promise to give him the kingdom and make him the head of a royal dynasty (1 Samuel 16). At this point in the story—hiding out from the murderous Saul in desert caves, acting insane to escape the Philistines—this promise seems laughable. Despite present appearances, however, David still believes God’s word, so much so that it causes him to praise God (vv. 4 and 10) even while he is still neck-deep in dire circumstances.
A Powerful Trust in God
With this trust, David confidently speaks out: “I shall not be afraid. What can flesh do to me?” (v. 4). In v. 9 he states that his “enemies will turn back” because he calls on the Lord as his deliverer. In vv. 12 and 13, David offers up a thank offering, saying to God, “you have delivered my soul from death.” David is so confident of his deliverance that he speaks of it in the past tense. That confidence is not based on guesswork, sketchy prophecy, or bravado; it is appropriate only because God has already told David what He has in store for him.
David actually takes God at His word and acts upon it, even when the circumstances don’t seem to match. For David, this means stepping out of the cave while the odds still seem stacked against him. He continued the fight that eventually culminates in his ascension to the throne of Israel (2 Samuel 5:1-3). That is trust in God.
Not Just for David
We too are called to trust God in a way that is every bit as real as David’s trust. Just as David hears God’s word through the prophet Samuel, so too we have a sure word, for the Bible is God’s very word to us. It is the vehicle through which He reveals His will and in it He makes countless promises to us. Our trust is firmly founded in this God who speaks.
We trust in God by believing in what He has said and, no less importantly, by believing that He actually intends to fulfill His word. Hebrews 10:23 tells us that our hope is well-founded because “He who promised is faithful.” Just like David, our hope is based on God’s faithfulness, not our present circumstances. So let’s step out in faith like David, praising God for who He is and living lives that show we believe He will accomplish all his good purposes, just as He said He would.
