As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
From Rock to Stumbling Block
Studies of Peter
Peter went from rock to stumbling block within the same chapter (Matthew 16:21-28). After this event he would go from that to worse, denying Jesus. We all experience ups and downs in our faith journey. There will be times when we see Jesus as Messiah and become like Peter, rock of the Rock. There are also times when we look at events around us and cry out, “Bad things like this are not supposed to happen!” Pastors know that they will sometimes be crucified or disowned, even by close friends. Of course, being crucified is something that other Christians also experience. When our fellow Christians are persecuted, are we tempted to lose faith or cry out to heaven in objection? Let us not stumble but remember that carrying our own cross of crucifixion is part of the Christian journey.
