When God is in pursuit, asking him for a sign is not an act of unfaithfulness. Just think about Gideon (Judges 6:36), he wasn't happy with just a wet fleece on dry ground, he asked for another sign! Typing of which, do you have a Bible? If not, I suggest you get one. I'd recommend either The Message or NIV for starters. Also, Romans is a great place to start to read, as is the four Gospels (Luke is probably one of my favorites).
JLAP, I am happy for you. I also will welcome you into the family of Christ. A word of cation, don't resist change. And don't think less of your decision just because you felt that it was based on the fear of hell. I for one will not make fun of you for that. You have my word. There are many reasons why to accept the Grace and Forgiveness of Christ, and not one would cause God to abandon you. May your Faith grow in leaps and bounds over the next few months. May your Faith endure trials and testings, and endure times of unceasing Joy. May I someday rejoice with you at God's throne in Heaven, unstained, and made anew. God be with you. Amen.
I'll be praying for you, and am here if you need to ask questions. Not, saying I would have all the answers, but hopefully I could help.
