But Moses said to God, “Who am I that I should go to Pharaoh and bring the children of Israel out of Egypt?” —Exodus 3:11
Even Moses went to God with his insecurities as a man, so it's fine that you have them. Yes, Moses, one of the greatest leaders of all time felt paralyzed by his inability. While you may know this about Moses, do you know how he feels? If so, there is hope for these uneasy feelings, and the hope isn't found in believing in yourself. When you will see the impossibilities of your situation, you are centering your attention on your ability or lack of it. And these insecurities you have in yourself should drive you to God because your abilities are never the source of your strength. Your abilities have limits. In fact, in most cases, you can't do it. Therefore your insecurities are true and real. The key is to turn attention away from yourself and your capabilities, toward a God who can do everything and anything. Remember it is not about who you are, but who He is and that "He will be with you."
He said, “But I will be with you, and this shall be the sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.”—Exodus 3:12
DO THIS: Stop trusting in yourself, trust only in God.
PRAYER: God, I confess I have been too focused on myself, and therefore my emotions have been wild, and my focus has been entirely on myself. Today I trust in you, not myself. And may my trust and faith be evidenced by the world, and glory and attention brought to You and Your name.
