For God is working in you, giving you the desire to obey him and the power to do what pleases him. Philippians 2:13 (NLT)
Oh...so it's not just up to me to "work up" the desire to do what He wants me to do? Boy, that's good news! This verse tells us that not only will He give us the desire to obey, but He also gives us the power to do what pleases Him. He really did think of everything, didn't He?
