Our self-esteem is based on the value God places on us. It's in the Bible, Psalm 8:3-5, NIV. "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have set in place, what is man that You are mindful of him, the son of man that You care for him? You made him a little lower than the heavenly beings and crowned him with glory and honor."
God values us based on His character, not ours. It's in the Bible, Psalm 113:7-8, NIV. "He raises the poor from the dust and lifts the needy from the ash heap; He seats them with princes, with the princes of their people."
God values us and we're constantly on His mind. It's in the Bible, Psalm 139:17-18, TLB. "How precious it is, Lord, to realize that You are thinking about me constantly! I can't even count how many times a day your thoughts turn towards me. And when I waken in the morning, You are still thinking of me!"
We are valuable to God. It's in the Bible, Luke 12:6-7, TLB. "What is the price of five sparrows? A couple of pennies? Not much more than that. Yet God does not forget a single one of them. And He knows the number of hairs on your head! Never fear, you are far more valuable to Him than a whole flock of sparrows."
The key to an honest and accurate evaluation is knowing the basis of our self-worth—our identity in Christ. It's in the Bible, Romans 12:3, TEV. "Do not think of yourselves more highly than you should. Instead, be modest in your thinking, and each one of you judge himself according to the amount of faith that God has given him."
