A lot of people think that to say Christians have a changed relationship to the truth means that Christians become honest. It’s not less than that. Technical, ethical honesty is one thing. But we’re talking about something more and deeper.
In Ephesians 4:15, Paul says, “speaking the truth in love.” But what Paul actually says in Greek is, “truthing in love.” He turns a noun into a verb. It’s an awkward phrase. And it harkens to a place where Jesus speaks of his followers as people who are of the truth, sort of made of truth, swimming in truth. It means a supernaturally changed heart is a heart that has an attitude and relationship to truth that no other kinds of hearts have.
What are we talking about? In this great passage, we see 1) the problem of truth, 2) the encounter we have to have with truth, and 3) something about the practice of truth.
