This week we read as John warns the church about the false teachers who might rise up to deceive them. Many in John’s day and in our modern world preach in the name of Jesus—but how are we to know who to believe and who to trust? How do we know if a teacher, messenger, or pastor is from God? John gives his people two tests, centered on Jesus. The “Jesus Tests” help us to know whether someone teaching us is in line with God’s truth. Many of us have our own tests that we have created over a lifetime of listening to Christian teaching, radio, music, and church services. John centers his test on the truth of Christ. We know that we are of God—and that those we listen to are from God—when the truth of Jesus Christ is made clear in our lives in both word and deed. All other tests might fail to truly show what is behind the scenes, but as John says, “every spirit that confesses that Jesus Christ has come in the flesh is from God. And every spirit that does not confess Jesus is not from God.” Live by the Spirit, and you will confess Jesus Christ in word and deed.
