I had the awesome priviledge of leading one of my "former students" in the sinners prayer the other day in my office.
I hope you have experienced what that is like. It is phenomenal that God would allow me and you to be used in that way.
Don't hesitate to give an answer for your faith. Don't be shy about sharing your faith. Don't feel inadequate to lead someone to make the most important decision of their life.
Eternity matters!
