2 Peter:1:17 when he received honor and glory from God the Father. The voice from the majestic glory of God said to him, “This is my dearly loved Son, who brings me great joy.” 18 We ourselves heard that voice from heaven when we were with him on the holy mountain. 19 Because of that experience, we have even greater confidence in the message proclaimed by the prophets. You must pay close attention to what they wrote, for their words are like a lamp shining in a dark place—until the Day dawns, and Christ the Morning Star shines in your hearts. NLT
The prophets spoke by the power of the Holy Spirit of things they had not themselves seen. Peter is a witness that speaks from personal observation and experience that confirms what he what he has previously only known by word-of-mouth from the prophecy of the prophets.
Prophecy is “pre-seeing” but prophesying is something different. Prophesying is not just knowing what is predicted but speaking of the witness of the Holy Spirit in your personal observation and experience. I write to you today from personal awareness of the gap that exists between all I know should be a part of my life of faith and the reality of my heart’s desire to honestly be able to prophesy Peter’s encouragement to you. “You must pay close attention to what they wrote,for their words are like a lamp shining in a dark place—until the Day dawns, and Christ the Morning Star shines in your hearts. NLT
That is the one relationship that fills the gap between what we know but have not personally experienced and what we speak. That’s what makes the words from these other witnesses the prophesy of the Holy Spirit at work in our lives,
and that is what confirms the truth of our witness.
