Mary was young, poor, and a woman--not qualities the intelligentsia would have chosen to bear the Most High's Messiah.
We don't know if she was plain or stunning but, spiritually, she was all God's--available to His wisdom and strength. God assigned her to be the perfect mother for His Son. Pure, astute, and willing, she chose to lay her will under God's.
Whether 16 or 62, on food stamps or a 400K salary, woman or man, God chooses us for special jobs. He sees what we can't. The Almighty has ways to help us overcome the challenges. Our Lord doesn't measure like Wall Street or Washington, Harvard or Hollywood.
The Creator's eye, clear and infinite, sees what we can't. Our King reveals that He is looking for hearts completely given to Him.
FOR YOUR CONSIDERATION
The eyes of the Lord range throughout the earth to strengthen those whose hearts are fully committed to him (2 Chronicles 16:9, NIV '84).
Do you acknowledge that God chooses YOU for unique purposes for which He hand selected you? (See Ephesians 2:9-10.) How might God's measure of your suitability be different from your own?
Would God say you are fully committed?
