Change is inevitable. change is not always bad, neither is it always good. Change is a challenge, resulting in transformation in the likeness of Jesus (eg 40 days between Christ’s resurrection and His accession). Peter and others went back to what they were accustomed to until Jesus appeared. Peter was changed. Transformation is the change in the inner man, not in outward behavior. It is progressively becoming more deeply and intimately acquainted with Him – to be continually transformed into His likeness (Phil 3:10).
