In brief, from Abu Daoud (he links to the full article from Mission Frontiers):
- A sure salvation
- Jesus
- A Holy Book: the power of the Bible
- Then you will know the truth (Christianity teaches the truth about God, humanity and ethics)
- Dreams and visions (you can find out more about that here)
- The love of God manifest in Christ and the Church
- I have called you friends: relationship with God
- Persecution (both being persecuted and seeing others persecuted)
Thanks for posting this. I develop most of those themes more in this post:
