Acts 22 teaches us the power of our personal testimony of when we came to faith in Jesus Christ. Paul shares his experience with the Jews in the temple. They are angry and ready to kill him, but calm for a moment to hear his witness of Jesus.
Later, Paul will share his testimony with King Agrippa as he stands trial for his life. His passion for Jesus and his knowledge of the Scriptures come through with much power to convince even the worst skeptics.
Do not be shy about sharing the impact and change in your life when you gave your heart to Jesus. People will listen with interest. When they taste of Jesus some will fall in love with Him and follow Jesus with all of their heart.
