More childish comments, just like GT.
God gave Paul a dispensation of the gospel.
He certainly had a key role, but no, he did not give Paul a dispensation of the Gospel per se. He did enact one in Christ, but it did not hinge on Paul, nor was Paul the only one who knew. Paul usually speaks in the collective plural about all those who preach it, for ex., 2 Cor.
God did not give Paul a dispensation of the Gospel any more than he gave Moses a dispensation of the law. These are actually ages of time, and we know from Gal 4 why the Law was enacted as such (there are scholars who say it is one of several affirming most of the same tenets but still unlike the Gospel as far as how founding principles go. This is why so many similar laws can be found around the world, as in Lewis THE ABOLITION OF MAN, appendix on 'The Tao.'). So the 'world' in 'weak and miserable elements of the world' is wider than Judaism.
If you think about biblical history in its most succinct form you have: a very quick lapse into widespread, grievous evil;
followed by the deluge punishment;
followed by the Law as a shadow or tutorial about Christ;
followed by the current Messianic age of maturity in Christ.
We do not have the type of violent, degenerate evil of the predeluge period, nor do we have the child-trainer aspect of the Law, but we do have (even if uncredited) a general world situation where there is a relatively high value on person and property. The tipping point of course will be if the world thinks it is based on human choice or government rather than on a distinct God, because if it is human choice it all comes down to large government who can shift it around as they please. In that sense, 'God is not good' unless it is the distinct Creator on whom dignity and property are based.
