1st Corinthians 15:12-22 Union with Christ: Glorification (December 24, 2025 AM, Dr. Michael Grasso)

"In this sermon from 1 Corinthians 15:12–22, we explore Paul’s profound teaching on the resurrection and how it flows directly from the doctrine of union with Christ. Every benefit of salvation—justification, adoption, sanctification, and now glorification—comes to us because we are united to Christ, the second Adam and our covenant head.Some in Corinth denied the resurrection of the dead. Paul responds by showing that to deny our resurrection is to deny Christ’s resurrection, because the two are inseparably linked. Christ is the firstfruits—the beginning of one great harvest. His resurrection guarantees ours. Your future resurrection is not only promised; it has already begun in Him.This reality transforms how we endure suffering in this life. Just as Christ entered glory after humiliation and suffering, so believers—united to Him—follow that same pattern. Our sufferings are “with Christ,” and our glorification will be with Him as well.At Christmas we remember why this union is possible at all: the incarnation. The eternal Son became man so that we could be united to Him and share in His life, His righteousness, and ultimately His resurrection. As we have borne the image of the man of dust, so we will bear the image of the Man of heaven.If Christ is raised, then you will be raised. If you are in Christ, you will live.This is the hope, the comfort, and the unshakeable foundation of the Christian life.#1Corinthians15 #UnionWithChrist #Resurrection #ChristianSermon #BibleTeaching #Glorification #ReformedTheology #GospelHope #Incarnation #ChristTheFirstfruits #EternalLife #ChristianLiving"
