Buddy learned Colossians 3:23 when we started his chore chart a few weeks ago. This verse is at the top of his chore chart and we would recite it as he would begin his chores. I did not plan any specific activities to go with this verse but he learned it rather quickly.
Any time that we would work around the house, Buddy and I would talk about how we should work enthusiastically and work to the best of our ability. While he may not completely understand these concepts about working hard now, I hope that by learning Colossians 3:23 he will have a right attitude when he is older about work.
