Ephesians 6:5-8

5Bondmen, obey masters according to flesh, with fear and trembling, in simplicity of your heart as to the Christ;

6not with eye-service as men-pleasers; but as bondmen of Christ, doing the will of 1God from [the] soul,

7serving with good will as to the Lord, and not to men;

8knowing that whatever good each shall do, this he shall receive of [the] Lord, whether bond or free.
