"Whatever you do, work at it with all your heart, as working for the Lord, not for men." (Colossians 3:23)
Several years ago, my art work was not bringing in enough money, but I was reluctant to give up and get a 40 hour a week job. There was a woman in my church who cleaned houses, and she was wanting to cut back some. She kindly offered three of her houses to clean. I gratefully accepted. She explained that she needed me to come with her to clean these houses, so that she could train me. I thought, great, like I need training to clean house.
As she trained me, it became obvious that this was not just cleaning to my friend. This was worship. She told me, I always clean with all my heart, as unto the Lord. This is my sacrifice to Him. She also prayed for the families while she cleaned their houses. Wow.
I got a whole new perspective, and learned such a powerful lesson. Anything you do, from writing a song, sculpting, or sweeping the floor is elevated to something sacred when you do it with all your might unto the Lord.
