Not that we are sufficient of ourselves to think of anything as being from ourselves, but our sufficiency is from God. (2 Corinthians 3:5)
You won't have to lift a hand in this battle, just stand firm, Judah & Jerusalem, and watch God's saving work for you take shape. Don't be afraid, don't waiver. March out boldly tomorrow - God is with you. (2 Chronicles 20:17)
Sometimes we can get bogged down thinking that we do not have what it takes to accomplish the task at hand, or walk down the path set before us. Faith and action go hand in hand that is true. However, God does not leave us alone in action. The moment we take a step, He is right there giving us the strength. This knowledge is too wonderful for our minds to fully comprehend I think. Dear ones, please know that our strength, our sufficiency is not our own, but HIS. Walk therein and know that you will finish the race in HIS strength.
