Perched high on the climbing wall, Sarah could feel panic rising as her weakening fingers began losing grip on the handholds. Just how hard will I hit the ground? she wondered.

But the instructor kept calling out assurances from below. As the “belayer” tethered to the other end of the rope tied to Sarah’s harness through a pulley, his weight would hold her if she fell. “I’m much heavier than you!” he yelled. “Just let go.”

So she did—and simply swung away from the wall to dangle safely in the air.

The incident gave Sarah a new perspective of the picture of God in Psalm 18:2: “The Lord is my rock, my fortress and my deliverer; my God is my rock . . . my stronghold.” Sarah observed, “God is so much heavier than all my problems. I can let go of my worries and fears, and He’ll catch me.”

King David sang the words of Psalm 18 after God rescued him from “deep waters”—these were his “powerful enemy” looking to bring about his “day of . . . disaster” (vv. 16-18). Even if his troubles didn’t disappear, he knew he could trust his all-powerful Savior and that God was holding on to him tightly.
