Why did God make me short / tall?
Here's the answer:
God wants you to praise Him about the wonderful way He created you.
Suppose you are drawing a picture of children playing outside. You don’t draw all the children to look exactly the same! You draw some girls and some boys. You draw some with straight, blonde hair, and some with curly, black hair. You draw some tall and some short. You would be surprised if one of your drawings folded his arms and grumbled, "I wanted to have brown hair and green eyes. You messed up!"
It would be silly for a drawing to complain about the way you made him. In the same way, we need to trust God for how He made us!
In the Bible, King David said, "You created the deepest parts of my being. You put me together inside my mother’s body. How you made me is amazing and wonderful. I praise you for that. What you have done is wonderful. I know that very well" (Psalm 139:13–16).
When Amy Carmichael was a little girl, she prayed that God would change her brown eyes to blue. When she grew up and became a missionary to India, she was thankful God kept her eyes brown because they matched the color of the other women there. Gladys Aylward, another missionary, always wondered why God made her short until she went to China and was the same size as the Chinese women.
God also has a good purpose for how He created you. You may never know His purpose, but you should still trust and praise Him.
"Braiding your hair doesn’t make you beautiful. Wearing gold jewelry or fine clothes doesn’t make you beautiful. Instead, your beauty comes from inside you. It is the beauty of a gentle and quiet spirit. Beauty like that doesn’t fade away. God places great value on it" (1 Peter 3:3–4).
"Charm can fool you. Beauty fades. But a woman who has respect for the LORD should be praised." (Proverbs 31:30).
