Some Christians doubt that God can use them, because they don’t have any great talents or skills. However, God doesn’t necessarily look to use people with great talent; He examines the heart (see 1 Samuel 16:7).
Paul wrote, in 1 Corinthians 1:26-27, Brothers, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong.
God often chooses to use lowly or seemingly foolish people so that He can show His greatness through them.
When you think you have it all together and have everything going in your favor, then you won’t lean on God–you’ll rely on your own strength. But if you know that you can’t do something on your own, then you’ll rely on God for strength–and that’s when God can show His greatness.
Every single person has amazing potential to do great things for God. Regardless of your talents, you can do outstanding things for God. All God is looking for is people like David, who have a right heart that is open and available for God to work through.
If you find yourself broken and in obvious need of God’s help, don’t despair. God can use you anyway, because God is not necessarily looking for ability; He’s looking for availability.
