That is the dominant, contemporary, sterile notion of truth. The notion that truth can be accumulated and stock-piled. You don’t even need to decide which parts of it are important, never mind act on it. Think Wikipedia.
But in Scripture truth is actualized and lived. And if it isn’t, then it isn’t truth yet —- not in a sense that matters.Deuteronomy, for example, urges the children of Israel, “Teach your children the Law and to do it.” The last phrase is added over and over again, because it stresses a fundamental truth about truth.
A truth doesn’t matter until you live it.
