A janitor at the University of Minnesota was a devout Christian who longed for his son Bob to put his trust in Christ. Bob recalls his father lovingly pleading, “Take Jesus as your Savior!”

Bob, a well-educated engineer, was moved but asked his dad to give some reasons why he should trust Jesus. His father had little education and could only say with tears, “All I know is that He is who He says He is. I love you and want you to know Him too.”

A simple, heartfelt testimony of our personal faith in Christ can be a powerful witness. But we need not stop at that point, no matter what our education. We have sound reasons to believe that Jesus is the Son of God.

Peter told believers they should always be ready to give a reason for their hope in Christ (1 Pet. 3:15). And in the book of Acts we read about the Spirit-empowered witness of Stephen and Paul (Acts 6:9-10; 24:24-25; 26:24-28).

What we say must be linked to a commitment to Jesus as Lord, and we must have a humble attitude, a clear conscience, and good conduct (1 Pet. 3:15-16). As we then rely on God, He can make people receptive to a discussion of why it makes sense to believe in Christ. A good life and good reasons make for a powerful witness.
