Peter boldly rejected Christ’s prophecy; he vainly exalted himself above the other disciples, saying, “Even if all are made to stumble because of you, I will never be made to stumble.”  Despite great effort, he would go on to deny the Lord three times before morning. Jesus promised that he would eventually send a replacement; after his resurrection and ascension, he fulfilled his commitment; Peter and the other disciples received the Holy Spirit on the day of Pentecost.  After receiving God’s Spirit, Peter’s strength was restored; he immediately entered a crowded temple and boldly preached the gospel.The Peter that denied Christ leaned on his own strength; the Peter that proclaimed Christ relied upon God’s power. For the sake of Christ, Peter went on to endure beatings, imprisonment, persecutions without number, and even death [he was crucified upside down in the city of Rome.]Without God, it is difficult to accomplish even the simplest tasks.  But with God, it is possible to move mountains.
