You are looking at this in the wrong light. It's a privilege to be able to have the opportunity to share the gospel with others and she is willing. The issue here seems to be whether you want to go down the road with her and see her come out the other end as a new creature in Christ and that can be like the proverb about the man who builds a tower, whether he is able to finish it. The highest rate of salvation comes from "Friendship evangelism. Sometimes God puts people on our paths to show us how to extend Christ's love toward those who live in darkness. I will be praying for Jenny.
