For God is working in you, giving you the desire and the power to do what pleases him.
Philippians 2:13 NLT

Even when strength feels like it is lost, we can’t always depend on feelings. Believe the word of God. He said he is working in you, let him. He said he is giving you the power and the desire, let him. Let him do it in you, follow his prompt voice, his gentle sway, his leading and go.
