Among people who discuss such things, truth is understood to be a function of propositions. While the terms truth and reality are sometimes used interchangeably in popular conversations, they are distinguished in technical discussion. As a function of propositions, truth is (roughly speaking) about reality, but it is not reality itself.
Since Christians affirm the existence of a real, created world external to themselves, they typically incline toward some version of the correspondence theory of truth. Stated simply, the correspondence theory affirms that a proposition is true if and only if what it asserts corresponds to reality. Suppose someone proposes that the sun is shining outside. That proposition is true if and only if the sun actually is shining outside. If the sun is not shining outside, the proposition is false.
The nature of propositions is to make connections. This is the difference between naming and telling: telling always involves some form of predication. Propositions assert the existence of links between facts (ideas and objects), activities, and concepts. Consequently, propositions are always interpretive, which means that they are always more than merely factual.
The connective nature of propositions is important because of the interconnectedness of the universe. Simply to point and say “cow” is not particularly useful unless the notion of a cow can be connected to other aspects of reality. By making connections between “cow” and the rest of reality, propositions not only factually assert “cow,” but they construe what a cow means.
Truth, therefore, is more than a matter of asserting existence (though even an assertion of existence is already an interpretation). It is a matter of rightly construing the various aspects of the universe so that their relationship becomes evident. It is a matter of putting facts and connections in the right contexts. These contexts include not only material reality, but also moral and personal reality. read more
