How did the gift of the Holy Ghost help the Apostles in their responsibility to be witnesses of Jesus Christ? (See John 15:26–27; 1 Corinthians 12:3.) What is the role of the Holy Ghost in our efforts to teach the gospel? (See 2 Nephi 33:1; D&C 42:14.)
How did Peter respond to those who mocked the Apostles for speaking in tongues? (See Acts 2:14–24, 36.) What impresses you about Peter’s response? Why is it important to have a testimony of Jesus Christ and his divine mission? How can the Holy Ghost help us share our testimonies?
Peter used a miracle as an opportunity to testify of Jesus Christ (Acts 3:12–26; 4:5–12). What opportunities do you have to testify of Christ? How have you been blessed as you have been a witness (or have heard others be witnesses) of Jesus Christ?
Read Mosiah 18:8–9, giving close attention to the instruction to “stand as witnesses of God at all times and in all things, and in all places.” Ask family members how they can follow this instruction. Have a family member relate an experience he or she has had in being a witness of Jesus Christ and his gospel. Encourage family members to be witnesses of the Savior in the things they say and do during the coming week.
