God has dealt differently
with mankind during different eras of human history. That is not disputable. It
is evident to anyone who reads the Bible with anything more than cursory
attention.
How we think about this truth
is not one of those issues too heady and esoteric for anything but the rarefied
atmosphere of a roomful of full-time theologians. It determines how the average
believer reads the Old Testament, how he uses it, and the place he gives to it
in the Christian life. It may affect how he thinks about the nation of Israel. It
molds his expectations about the millennial kingdom of Jesus Christ. It
certainly impacts how we read the Sermon on the Mount.
And it does all these things and others to us even if we have not consciously developed our theology with
respect to the various periods of human history.
