But while the devil is a tireless worker, “accus[ing our brothers] day and night before our God,” we know that his lies will ultimately prove ineffective. We know this because he is no match for Jesus Christ, the true witness, the one who tells us the truth about us by claiming us as God’s own. And because Christ speaks the truth, the Christian, too, is summoned to a vocation as courageous truth-teller. She does this first of all by bearing witness to the gospel, but also through a quiet passion for truth in everyday life. “You shall not bear false witness against your neighbor” (Exod. 20:16). This commandment of the law is also integral to the gospel. Whenever the Christian refuses to go along with the devil’s lies, she confirms her love both of the true witness and of the neighbor who suffers the burden of false witness. The “necessity” of lying is grounded in the structures of the old eon. But that eon is passing away. In a world where truth (Christ) is victorious, there is no reason not to speak the truth.Mangina, Joseph L. Revelation. Brazos Theological Commentary on the Bible.
