Or maybe just present the gospel and let the Holy Spirit do the convicting, (instead of an altar call) then if the situation arises, give them the help they need by answering any questions and then lead them to a good bible believing church.

Jeremiah 23:16,17, "Thus says the Lord of hosts: “Do not listen to the words of the prophets who prophesy to you, filling you with vain hopes. They speak visions of their own minds, not from the mouth of the Lord. 17They say continually to those who despise the word of the Lord, ‘It shall be well with you’; and to everyone who stubbornly follows his own heart, they say, ‘No disaster shall come upon you."
