To pray is to bring the power of God into your witness. God has given you a testimony to tell others, but how to use that testimony is up to God. The only way to find out what God needs to use of your testimony in your witness is by praying for the wisdom to speak only the words that need to be said to bring your conversation to the point of a choice for or against Jesus Christ. God will lead the unbeliever’s heart to acceptance of Christ.
If we do not pray for the strength and wisdom of God before witnessing then we will stumble in our words and sound as if we have no idea what we are talking about. This could leave the unbeliever more confused and skeptical about his need for Jesus. People usually won’t listen for too long if they have to think too much; confused explanations only add to the lack of attention in others to hear what is being spoken. Jesus said, “Where two or three are gathered, there I am.” Praying for or with the person you are witnessing to will bring Jesus into the conversation where He can now begin to guide your words and melt the heart of the hearer. Only Jesus can bring salvation to another. By praying first, we take ourselves out of the equation to let Jesus be in the lead.
