Truth is progressive
Truth is progressive. This is one of the best spiritual concepts I learned from Dr. John Write Follette's teaching. I wish I had had the opportunity to hear him teach in person, but I settled for all the books and cassette tapes I could get my hands on. He was one of the first spiritual leaders I encountered who didn't feel the need to present themselves as a preacher or evangelist. He was just a Bible teacher and a great one at that.
Truth changes as we discover it, grow in it, and continue to build on what we know to be true. Our doctrines on Heaven, Hell, justification, redemption all everything in between is incomplete. Unless we allow those concepts to grow and evolve in our mind and spirit, we will just have the law. We should never build our life on doctrine alone. Its knowledge and experience that form a solid foundation for spiritual growth.
