Sunday with my son

I love spending time with my only son. He's 11, he's funny, and he loves many of the same things I do. After spending much of the last 7 days without him, we had a blast playing Wii and watching hockey, basketball, AND baseball. Is it a waste of time to do this for hours on a Sunday afternoon? Well, obviously, you could get arguments from all over the board, but I'm only concerned with two arguments - one from God's Word and one from my son. What does the Bible have to say about how to spend Sunday afternoons? Well, directly, nothing much, but it does give us plenty of help: Whatever I do, it should be done with thanksgiving to God and in the name of Jesus (Colossians 3:17). Whatever I do that is not done by faith is sin (Romans 14:23). Whatever I do ought to be done as an ambassador of Jesus Christ (2 Corinthians 5:20). As a follower of Jesus Christ, I need to simply be with my son and love on him - it may not be the way other father/sons spend their time together, but it's what we do. May I send my son away to college (or leave this earth before that time) knowing that we spent LOTS of time together being Jesus to each other and that he was trained to do the same with others. I won't leave anything to chance.
