Many of us have grown up in churches where we have been encouraged to share our faith. Unfortunately, this may not come naturally to a lot of people. Someone taught us a way to share one's faith that is a way to organize it in one's mind should the opportunity arise and you forget what to say.
Obviously, you're not going to say this acronym as you share but it helps to remember it for yourself to keep you focused and on track.
The acronym is RAMP and it stands for Resurrection, Apostles' witness, Miracles, Prophecies. You talk about the resurrection of Christ, how He stood and died in our place for our sins bc we're all sinners. There were more than 500 eye witnesses to His resurrection. While on earth He performed more miracles than any book could hold. Miracles still point to Him today. There were more than 300 prophecies about Him before He came to earth. I might be wrong as to the number of prophecies but you get the general gist.
That's the simplest way I know to share one's faith. Usually, I share more of a personal testimony and how Christ has changed my life but this is a good one for apologetics and if you forget some of the basic reasons for belief in Christ.
Hopefully that helps someone who may suddenly blank out when they're given a great opportunity to share their faith!
