o not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus." Phil. 4:6-7 ESV
Once we have prayed, we may depend on God, confident in the peace that He promises.
Like leaning against a wall and knowing it will support our weight, we may lean on him. When we draw nearer to him, he comes closer to us. He's not going to step aside and let us fall when we lean.
