When we lean on our own understanding, we rely on ourselves, our wisdom, and our plan. Think about it, what happens when you lean on something? You rest your weight on it, expecting that it will steady you and hold you up. But our understanding isn’t always strong enough to lean on. We don’t see the whole picture, so we can’t understand the whole plan.
There is a great relief we experience when we release our need to understand and just trust God anyway. If you’re hurting, don’t lean on your own understanding, lean on God instead. You don’t have to understand everything to trust God with every thing.
