The Lord has proclaimed that His doctrine shall be established through the testimony of multiple witnesses: “In the mouth of two or three witnesses shall every word be established” (2 Corinthians 13:1; compare Matthew 18:16; D&C 6:28; 128:3; 2 Nephi 11:1–3). There is power in testifying as a witness for the Lord and in blending our voices with others to confirm the truth of the gospel of Jesus Christ.
