Welcome, Naomi. My own daughter was saved at about your age at a youth gathering with two or three of her friends, so your story sounds familiar. I pray that we can be an encouragement to you and help you grow in your faith.
I was moved at a conference with 4 of my closest friends and all of us were saved that night except one friend who had given her heart to God a few years earlier but had been praying for 3 years that we would get saved her prayers were answered!!!
