It hasn't worked out because, well, it's hard on my ego. I sit down with the boys to play - usually on Sunday afternoons. Our session usually consists of them yelling at me for not doing the proper thing quickly enough. My oldest tends to get frustrated and ask "Do you want me to do it for you?" I usually reply, "Look, I'm busy working to pay for the electricity to run this thing. I don't get to sit around and play it all the time." For good measure, I usually run to the front door and yell, "Get off my lawn!" at all the neighborhood kids.
Here's the point - many of us are in the same trap with the Bible. We sit around and look at others who seem to have all the answers. They look at life and see things that we don't. Their perspective on issues is different than ours. They have the right answers at their fingertips while we fumble around and never seem to get it.
There's a reason. They have been taking God's Word and using it. Repeatedly, day after day, they have been taking what God says and applying it to their life. Sometimes they get it right. Sometimes . . . not so much. Through it all, they keep working at it. And over time, by constant use, they've trained themselves to use it. That's the point of Hebrews 5:14:
But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.
Maybe you've gotten frustrated at times with the New Testament Challenge. You don't seem to understand as much as you want or you can't figure out how to "make it work." Be patient. Persevere. Through constant use, you'll start to get it.
