Embrace the paradox of God's sovereignty and man’s responsibility. The sad thing is that some embrace the sovereignty of God over the human will and say: “It is wrong to portray God with His arms stretched out, inviting and calling.” And others embrace the responsibility of man and say, “If God invites and calls and beckons, then he can’t really be sovereign over man’s will, and man really is ultimately self-determining and God is not really in control of all things.” Both of these are sad mistakes. It is sad, because one group rejects something deep and precious that God has revealed about Himself for our strength and hope and joy and love – namely, his absolute sovereignty. Oh, how sweet it is when all around our soul gives way, and we need a reliable and firm rock in a world that sometimes seems utterly out of control and meaningless and cruel. Oh, how sweet at these times to know that God is not good and helpless, but good and sovereign. And the other group (who embrace the sovereignty of God) sometimes rejects something utterly crucial for understanding the justice of God in dealing with people, and they fail to see how we should plead with people and persuade people and invite people and woo people with tears, to Christ, and on behalf of Christ.
