Ephesians 6:5-9 is quickly summed up by saying, "work hard at your job." I feel like I do that. I've always been known as a hard worker, a good employee. But I think there is a level I don't work at that this passage points to. I work to "please people." I work to please my bosses and the customers. I don't work as a "servant of Christ, doing the will of God from the heart, rendering service with a good will as to the Lord."
We need to be working as though we are working and serving God. Our mind set need to be that we are doing our best for God not man. Work hard. But work for God. Don't work to please man so you can get that raise or promotion. Work to please God and glorify Him with your hard work and great performance.
Praise God for His Leadership.
