John 2:20-22 NIV
They replied, “It has taken forty-six years to build this temple, and you are going to raise it in three days?” But the temple he had spoken of was his body. After he was raised from the dead, his disciples recalled what he had said. Then they believed the scripture and the words that Jesus had spoken.
John 2:23-25 NIV
Now while he was in Jerusalem at the Passover Festival, many people saw the signs he was performing and believed in his name. But Jesus would not entrust himself to them, for he knew all people. He did not need any testimony about mankind, for he knew what was in each person.
