Philippians 4:13 says, "I can do all things through Christ who strengthens me." Aren't you thankful today that it doesn't say, "Some things through Christ who strengthens me"?
In other words, if God calls you to do something, you don't have to be afraid. It can and will be done. Whatever He is calling you to do, remember that it's God who's calling you, and He will equip you, and He can do through you what you can't even do in your strength. So settle it in your heart that you can do all things through Christ who strengthens you.
The truth of God's Word is that whatever Christ has asked you to do, whatever mountain you have to climb, or whatever valley you have to go through, whatever it is, you can do it because Christ is the one who will give you the strength to finish. Oh, my brother, my sister, it's an incredible truth. Talk to God about it today.
Remember now, it's time to pray.
