I read this excellent short devotional today:
“Humble yourselves under the mighty hand of God, that He may exalt you in due time, casting all your care upon Him, for He cares for you” 1 Peter 5:6-7

Be full of confidence not in yourself or what you can do, but in the Lord and what He can do. Your life, once given to Him, is in His hands, not yours. Live in His strength, not yours. Depend on His resources, not your own.

“Do not cast away your confidence, which has great reward.” Hebrews 10:35.

How do you cast your care on Him?

Get out your “fishing pole of faith.”
Tie a hook to the line of your fishing pole.
Take all your cares and put them on a hook.
Cast the line as far as you can into the sea of God’s faithfulness.
Cut the line and leave them out there.
Take “I can’t” out of your vocabulary, and replace it with “God can!”
