Christians? is it true that Jesus christ believed the end of the world would be in his time?

Again the high priest asked him, "Are you the Christ, the Son of the Blessed?" And Jesus said, "I am; and you will see the Son of man sitting at the right hand of Power, and coming with the clouds of heaven." And the high priest tore his mantle, and said, "Why do we still need witnesses? You have heard this blasphemy. What is your decision?" And they all condemned him as deserving death. And some began to spit on him, and to cover his face, and to strike him, saying to him, Prophesy!" And the guards received him with blows. {Mark 14:61b-65 RSV}
