Our stress comes from trying to do it all. Peace comes from giving it to the One who will take care of it all. He wants us to depend on Him. We cannot be the kids God needs if we are stressing all the time. Lay whatever is stressing you at the cross and leave it there. Let it all go and let God have it. Now take a deep breath and feel peace that only He gives.
Do not be anxious or worried about anything, but in everything [every circumstance and situation] by prayer and petition with thanksgiving, continue to make your [specific] requests known to God. Philippians 4:6 AMP
Casting all your cares [all your anxieties, all your worries, and all your concerns, once and for all] on Him, for He cares about you [with deepest affection, and watches over you very carefully]. 1 Peter 5:7 AMP
