What is the whole comprehension of Paul's gospel?
Paul's gospel centers on God pouring out His grace upon the whole world, not merely America or Israel. Believers are therefore responsible to tell the world that God's grace reaches even the vilest person, because grace always exceeds abounding sin. The believer is not under law but under grace.
Les explains that the whole comprehension of Paul's gospel is that God has poured out His grace, not only upon America, not only upon Israel, but upon the whole world. That reality becomes the believer's responsibility: to let the world know that God's grace reaches to the vilest person. Les connects this to the earlier point that where sin abounds, God's grace is always greater. He illustrates with Dwight L. Moody, who preached on the grace of God in Chicago. After the audience left, a poor old reprobate sat weeping on the back row. He told Moody not to tell him God's grace could help him, because he had been a recruiter for the prostitution trade in Chicago; through him countless young girls became drug addicts, alcoholics, were murdered, or committed suicide. Moody replied, "That's the grace of God." Les says this is probably as good an example as he can find, other than Paul himself, that God's grace can go far beyond the most vile sinner we can dream of. It is incomprehensible and almost unbelievable, except that the word clearly declares it: believers are not under law but under grace.
