Would you invest lots of money in a failing company? Would you put someone in charge of your kids if they were irresponsible? Would you continue to give an employee responsibility when they've failed you a dozen times.
Too risky, I would imagine. The consequences are too great. Failure is too much to bear.
Funny, risk is one of the core features of God's relationship with us ... God invests heavily in our lives, he assembles us together into church communities, and he gives us immense vision. I guess we fail 99 out of 100 times. And, then he continues to risk with us, depending upon our success in that 1 time out of 100. He puts us in charge.
Far too many Christians imagine their relationship with God and His mission to be the safest activity of the week. Perhaps that's why we never change, and that's why we never risk with others, and that's why we spiritually fail.
Risk is an essential element of our relationship with the Father, and if we are going to participate in the Father's business, then lots of risk will be needed. We will need to change, we will need to take chances, we will need to put incompetent people in charge of things, and we will need to invest heavily in people that may very likely fail ... just as God is doing us.
