Others may feel that their spiritual growth is stunted because they don't play a visible role. This is also wrong. Sometimes those who are growing the most may feel inferior to those who maintain a hypocritical perfection. Spiritual comparisons are always unwise. Only the Lord is the true judge of spiritual growth.
Physcial stature doesn't matter, but our spiritual standing does. If you are feeling spiritually superior or inferior, ask God to give you the proper attitude. He is the true judge of the heart. The very common dangerous thing that causes most of the fall is the word called "self-deception".
