Tell what is true
Jesus told a restored man to tell his household what the Lord had done for him (Mark 5:19). Paul recounted his encounter with Jesus in Acts 22. A testimony is a witness to what you have seen, learned, and experienced. It does not need dramatic details.
Explain who Jesus is to you now: the Christ, the Son of God, crucified and risen. Describe a concrete change, such as making restitution, forgiving, leaving deception, or learning to love someone you avoided. Admit where obedience is still difficult.
Keep your story in its proper place
Your feelings and sequence of events are yours. Do not make them a universal conversion formula. When people in Acts 2 asked what to do, Peter told them to repent and be baptized in the name of Jesus Christ for forgiveness, with the promise of the Holy Spirit (Acts 2:37-41). He did not lead them through a sinner’s prayer.
Avoid exaggeration. Protect other people’s privacy. Do not describe a former community cruelly to make your present faith sound stronger. Invite questions and say “I don’t know” when that is the truth.
Practice in two minutes, then be willing to spend an hour listening. Continue with how to share the gospel with a friend and conversion accounts in Acts.
