Verse from Ephesians

Not with eyeservice, as men-pleasers, but as bondservants of Christ, doing the will of God from the heart. —Ephesians 6:6
If we do our work merely to earn a paycheck or satisfy a supervisor or a lecturer or a person such as a leader in church or cell group, we will fall short of the highest motivation—doing our best as evidence of our devotion to God. So, why do we work? we work “to the glory of God.”
