2 Peter 1:15: And I Will Make Every Effort So That After My Departure You May Be Able At Any Time To Recall These These Things.
Peter was a responsible leader in the church. He was an apostle. We are reminded that the first Christians devoted themselves to the Apostles' teaching (Acts 2:42). Throughout all of the years of church history, one of the constant things that we see amongst those who are faithfully following the Lord is a devotion to the teaching given by the Apostles. This includes this letter that we call 2 Peter.
