speak freely

"Rather than trying to learn all the right words, have all of the right booklets, anticipate all of the right questions, and memorise all of the right intros and scripture, we should approach evangelism with wisdom. This means we become people who incarnate the gospel and speak of it freely because our hearts and minds have been captivated by it. Becoming people of wisdom and compassion is the prerequisite for any evangelistic technique. "
