12:39 seeketh after a sign. “Sign” is the same word as “miracle.” This rebuke from Christ seems applicable to those Christians today who are continually looking for miraculous manifestations of one kind or another. We already have the completed Word of God, with abundant testimony to its inerrant authority, not to mention the tremendous scientific evidence of creation and historical evidence of Christ’s victory over death, so there is no need for further miraculous confirmation of our faith.
