Ours is not an age that desires to make long-term commitments. The covenant of marriage is often avoided, and vows that are made lack the permanence and commitment of former days. Guarantees are given for a very short period. Contracts are often vaguely worded or are undermined by loopholes and fine print. Strangely, Christians seem to think that clear, contractual agreements are somehow unspiritual, especially between two believers. ‘A man should be as good as his word,’ we are told. And so he should.
