Obey them not only to win their favor when their eye is on you, but as slaves of Christ, doing the will of God from your heart. Serve wholeheartedly, as if you were serving the Lord, not people, Ephesians 6:6-7 (NIV)
As believers we live to the Lord and our desire and goal is to please Him. Wherever we are stationed in life we do everything to serve and glorify Him.
Therefore we can always be and do our best in all our endeavors knowing that the one we are really serving is not men but the Lord who sees in secret but rewards openly.
Don’t be concerned about whether the people you’re working with, for, or under do not notice, appreciate or fully reward you for your input. As long as you’re sure that’s where the Lord called, placed, and wants you stay faithful and focused. Continue doing what you know is required of you wholeheartedly with excellence. Your real pay and reward is from your real Master the Lord in Heaven.
