Not if she listens to Joel Osteen.
Maybe not. Maybe God has someone else in mind to help her come to the Lord. He just happens to be in her vicinity and many receive the Lord through his ministry. Nevertheless,I have no doubt they'll be praying for her (and Houston).
If she went, she'd experience an anointing of worship, faith, hope, love, and the Good News of the Gospel of peace, God's Word. One thing she won't get is condemnation for who she is. Jesus notoriously looks past the sin (his blood allows him to do this) and see the need. Typically, homosexuality is the result of early-age rejection in some devastating form or other. God, by his power, grace and love, can reach these people. I pray He'll reach her.
