A person’s calling is essential. Look at how God chose David to be king instead of Saul. The anointing is the result of God’s calling. With God, He doesn’t look at age. Well, what does God look at? God looks at the heart. David is known as a man after God’s own heart.
In 1 Samuel 26:7, 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.”
When we see the life of King David, we can see he was also far from perfect. But God still chose him for a purpose. This is why God’s grace and mercy is so amazing. He chooses us despite our imperfections.
Scripture shows us that God also look at the heart of a person. Now I must say that if God was to really examine every little thing going on inside our hearts, He would find a lot of messy , complicated, and undesirable things inside all of us.
God has cleansed us and is still constantly sanctifying us through the forgiveness of sins in Christ Jesus. As long as we come before the Lord, the merciful God is always reckoning us as righteous in the eyes of God the Father.
