Christ's power was the priesthood. Himself a God had the power of God. May I bring to attention that He never exercised His power for His own convenience. Himself having several opportunities to do so, such as the 40 day fast. He could have used His divine authority to command the rocks to turn to bread, but He didn't. In the same breath He later multiplied loaves of bread and fish to feed a multitude. This power seems apparent that it was to be used for the aiding of the children of men. With this power He caused the lame to walk, the blind to see and eased the pains of those who were in agony, yet He did not impede the pain He endured in the Garden of Gethsemane or during His scourging done by the hands of men. Nor did He numb the agonizing misery of the cross or charge His angels to eliminate those who had hung Him there. His power wasn't to exalt Himself or to put Himself on a pedestal, but it was to lift those who were down trodden and to give hope to those whose hope had all, but gone and because of this He is put on the "pedestal". As great as this power is, He didn't keep to Himself. As Luke says, "Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases. And he sent them to preach the kingdom of God, and to heal the sick."
With the calling of the Twelve, Christ established His church. He inaugurated His church with prophets and apostles. Ephesians teaches us that His church is built upon apostles and prophets, Himself being the chief cornerstone. He also established a church for the purpose of taking the sacrament and for the perfecting and edifying the body of Christ (i.e. members of His church). He sent His apostles out into the world. For the first time He allowed the Gospel to be preached to the Gentiles. After His crucifixion and resurrection He ascended into Heaven and would later appear to others who were not in Jerusalem. Soon after His ascension the Church began to crumble. The persecution and the alienation of it's members from the gospel's truth is a main reason for the church's failure to survive. The persecution headed by the Romans and Jews was largely due to misunderstandings and fear of subjugation or in the least an attempt of revolution from a religious sect, most likely considered a cult. With the martyrdom of the apostles and the slaughtering of innocent believers of Christ God withdrew His authority and gospel from the Earth.
