Ephesians 6:6 Obey them not only to win their favour when their eye is on you, but as slaves of Christ, doing the will of God from your heart.
There are times in our lives when we go out and do things just because someone else is watching us or just because we want to be seen to do something. We go out and we try and please others by getting them to see us doing something.
That is hardly coming from the heart… more like trying to make someone desire something or to be jealous!
God does not want us to trick others, entice others or persuade others through what they see us doing. God wants us to do things for others because we want to do it from our hearts. The same focus we should have in doing things for God.
