It's a funny thing - when I'm crazed with work, spending time with my children relaxes me. Yet, at the end of a long weekend with them, the very thing I need to relax is a little work and time away from them!
It is one of the ironies of the ministry that the very man who works in God's name is often hardest put to find time for God. The parents of Jesus lost Him at church, and they were not the last ones to lose Him there.
