Colossians 3:22 Bondservants, obey in all things your masters according to the flesh, not with eyeservice, as men-pleasers, but in sincerity of heart, fearing God.
When we make a contract with someone we should keep it and we should obey the person in charge with everything they ask of us in a normal manner.
This does not mean we have to go against our beliefs when they tell us to do so – that is spiritual and we need to make sure we stick with God in those matters, not man!
But also to do things because we want to and not just because it’s our job; knowing that this is the will of God!
