My standard policy is to present and defend divinely revealed moral virtues and Christ's grace anywhere I am invited if my message is not curtailed. My participation was sponsored neither by Evangelical Ministries to New Religions nor Denver Seminary. I respect their inherent rights and treat them as I would want them to treat me. Like foreign missionaries, we need contacts with the people we seek to reach. Jesus explained that His disciples do good even to those who may oppose them.
Evangelism is the ultimate goal of Christian outreach.
After seeking to remove roadblocks in the way of faith, I invite people to believe the gospel and trust Christ. If they do not immediately receive the Messiah, I hope that in God's providence they will have taken a step in that direction. I keep several additional factors in mind. Differentiate a system of thought from its elements. Acknowledge both similarities and differences.
