a) Word used by a junior high youth leader when asking for testimonies from the group: "Dude, anybody up for a testimonium?"
b) A word of Christian testimony that includes the use of a musical instrument, preferably a harmonica.
c) The internal testimony of the Spirit to confirm within us the reliability of the Scripture, giving us certainty that the Bible is the Word of God.
Note: if this were a quiz and you didn't guess "c," you would be hopelessly wrong.
So what do you think about the concept of testimonium? Have you personally experienced it?
