David Powlison helpfully unpacks what trusting God means in Psalm 28:
Consider David’s Psalm 28. “To you, LORD, I call. My Rock, do not be deaf to me. If you don’t answer me, I will die. Hear the voice of my supplications, my cry for help to you” (vv. 1-2, AT).
This is an example of what it means to “entrust your soul” to the sovereign God. It’s not sedate. David does not mentally rehearse the fact that God is in control in order to quietly press on with unﬂinching composure.
Instead, trust pleads candidly and believingly with God: “This is big trouble. You must help me. I need you. You are my only hope.” Prayer means “ask for something you need and want.” Supplication means “really ask.” Frank supplication is the furthest thing from keeping everything in perspective so you can move on with life as normal.
The sovereign God does not intend that you maintain the status quo while suffering. Pain disrupts normal. It’s supposed to disrupt normal. It’s supposed to make you feel a need for help.
Psalm 28 is not an orderly “quiet time.” It’s noisy and needy. When you let life’s troubles get to you, it gets you to the only one who can help. As Psalm 28 unfolds, David speciﬁcally names the trouble he’s in, what he’s afraid of, what he wants (vv. 3-5). His trust in God’s sovereignty moves to glad conﬁdence (vv. 6-7). Finally, his faith works out into love as he starts interceding on behalf of others (vv. 8-9).
