God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
Those that God used in the past were just ordinary people with an extraordinary Master. They were not all champions of great faith, but little people who saw their own need, and put their small faith in a great God.
God is the source of all wisdom and understanding. He is the one who gives us discernment and insight. We can seek His wisdom in every decision we make and trust that He will guide us in the right direction. His word is a lamp unto our feet and a light unto our path.
