It is possible for us to submit and obey God when we choose to trust His plan. It is not impossible for God to work in and through us when we choose to believe Him. When God asks us to do things that in our own strength and humanness, we would rather not, God is able to do so much with our obedience and trust. We are not expected to do things in our own strength and on our own, we have a God of endless possibilities who is with us and for us and who knows best.
