Be comforted and challenged that God looks at things that the world does not look at . 1 Samuel 16:7. But the Lord said to Samuel. Do not consider his appearance or his height, for I have rejected him. The Lord does not look at the things people look at. People look at the outward appearance , but the Lord looks at the heart.
The heart matters, God can see it. The words and actions of a person come form he heart. The heart matters more than ability, talent and experience. God chooses those that have a heart to serve. It does not matter if you are weak or inexperienced, God will empower you and equip you if you have a heart do serve Him.
