I spent about 4 1/2 hours on my day off pressuring washing our back deck. It stretches the length of the house & is one of our favorite spots to sit and relax. After the falling leaves of autumn and the pollen of spring, it was pretty obvious that it needed to be cleaned. The results of my efforts were immediately noticeable and my wife & I were admiring how different it looked after I was finished.
I enjoy work like that-as much as I enjoy mowing & even painting (no sarcasm here-I really do like doing those things). I think the reason that those tasks bring so much satisfaction is that I can immediately see the results of my efforts. That doesn't happen quite as often when you are working in ministry-especially with youth. Sometimes you will labor for years before you see the fruit of something & then you may not see it at all.
This is the point where you simply trust that God has called you and that if you are listening to Him, He will produce the necessary results. It is a challenge to keep seeking God and His validation of what you do. It is more about being faithful to your calling than the immediately measurable outcomes.
