It’s hard to escape the word “truth” in this letter. John uses it six times in this very short letter.
What is he talking about when he says, “the truth”? Most likely, he’s talking about the truth of the gospel.
And John, after praising Gaius for walking in the truth of the gospel, tells him,
I have no greater joy than this: to hear that my children are walking in truth. (4)
What does that mean, to walk in the truth of the gospel?
I think it means to walk in the love and grace of God each day. To remember each day that God has rescued us from a life of sin that was destroying us. To remember that we are already accepted by him as his beloved children. And to live each day in gratitude and in awe of the grace that we have been given.
And if we walk in this truth daily, it puts a love in our hearts for God that transforms our entire life. It changes the way we think and the way we act. And people will notice, as they did with Gaius and Demetrius.
How about you? Are you walking in the truth of the gospel?
