For we are co-workers in God's service; you are God's field, God's building. - 1 Corinthians 3:9
Be imitators of God. - Ephesians 5:1
God can use anyone.
Am I now trying to win the approval of human beings, or of God? Or am I trying to please people? If I were still trying to please people, I would not be a servant of Christ. - Galatians 1:10
