Be of good courage, and he shall strengthen your heart, all you that hope in the Lord- Psalm 31:24

This is a promise that requires you to take a step in faith first.

It says that if you take courage, God will strengthen your heart.

He will strengthen your heart to fit the act that you are doing in faith. The grace will come to match the situation!

So even if you don't FEEL that courageous, go forward anyway. The Lord will come through for you.
