“Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.” Colossians 3:23-24 (NIV)
In Bible times slavery was being practiced and some instructions in the Bible are given to slaves. These words were addressed to slaves. But I believe the principles stated here can be applied to us today. Whether we are employed by an employer or helping others on a voluntary basis, we need to remember that as children of God we are serving Him. Just the activities of living can be considered as being done for his glory. And He is faithful in rewarding those who live for His glory.
