Everyone Who Acknowledges Me. That belief in the gospel is personal, as opposed to collective, is central to the Scriptures. Even the few times a collective response to the gospel is recorded, such as the conversion of the entire household of the Philippian jailer, the primary thrust is always personal and singular. “Then he brought them out and said, ‘Sirs, what must I do to be saved?’ And they said, ‘Believe in the Lord Jesus, and you will be saved, you and your household’” (Acts 16:30-31). The once-and-done verb in verse 31, “believe” is a second-person singular command, not plural. Also, the always-and-forever promise, “you will be saved,” is second-person singular, not plural. Furthermore, the extension of the salvation promise, “you and your household,” maintains its emphasis upon the singular and personal, which is to say: in the same way that the jailer believed and was saved, so also can his entire household be saved through their individual belief in Jesus Christ as the only Savior of sinners! The gospel is public; the faith-response to the gospel is personal.
However, personal faith that “Christ suffered once for sins, the righteous for the unrighteous, that he might bring us to God” (1 Pet. 3:18), is not private. It is not secret. It certainly begins in the hidden recesses of the heart, but it quickly and necessarily pours forth from the hidden heart into the public sector, usually beginning with water baptism, verbal testimony, and good works likened to “the fruit of the Spirit” (Gal. 5:22). “So, every healthy tree bears good fruit, but the diseased three bears bad fruit … every tree that does not bear good fruit is cut down and thrown into the fire” (Matt. 7:17, 19). The scenario of a healthy tree keeping its fruit private (i.e., hidden, secret) simply doesn’t exist. Personal faith becomes public witness.
Nearly constantly, the top fear listed by modern people is public speaking. It seems that ancient people, too, feared their ability to communicate in public what was dear to their heart. Jesus spoke comforting words to his disciples who were about to enter the public arena of two-by-two ministry: “Do not be anxious how you are to speak or what you are to say, for what you are to say will be given to you in that hour. For it is not you who speak, but the Spirit of your Father speaking through you” (Matt. 10:19-20). “It was not humiliation which early Christians dreaded, not even the cruel pain and the agony. But many of them feared that their own unskillfulness in words and defense might injure rather than commend the truth. It is the promise of God that when a man is on trial for his faith, the words will come to him” (William Barclay, The Gospel of Matthew). Do not court martyrdom, since Jesus allowed, “When they persecute you in one town flee to the next” (Matt. 10:23) yet “have no fear of them” (Matt. 10:26). “So, everyone who acknowledges me before men, I also will acknowledge before my Father who is in heaven, but whoever denies me before men, I also will deny before my Father who is in heaven” (Matt. 10:32-33). When the heart is healed, then the mouth will open.
