Although we are in Christ a new creation and free to live. In that freedom bring glory to His name. In His hands we are like instruments. He plays the right note when He needs us to do something , it is up to us if we want to live in harmony and respond to that note being played by God. By responding, we obey His command and share our faith if that is what is expected of us in that moment.
Live out your faith and be open to be used by God.
Be like an instrument in His hands.
