Real, positive change won’t come from a politically correct, relativist political class without some anchor in morality. In this quote, from Politics According to the Bible, Wayne Grudem makes it pretty clear what our society will need for change that means something:
Genuine, long-term change in a nation will only happen (1) if people’s hearts change so that they seek to do good, not evil; (2) if people’s minds change so that their moral convictions align more closely with God’s moral standards in the Bible; and (3) if a nation’s laws change so that they more fully encourage good conduct and punish wrong conduct. Item 1 comes about through personal evangelism and the power of the Gospel of Jesus Christ. Item 2 takes place both through personal conversation and teaching and through public discussion and debate. Item 3 comes about through Christian political involvement. All three are necessary.
Put another way, Christians are going to have to want to do good, encourage Biblical moral standards, and foster laws that punish wrong conduct.
We are going to have to have significant Christian influence on government.
