John 10:22-25

And it was at Jerusalem the feast of the dedication, and it was winter. And Jesus walked in the temple in Solomon's porch. Then came the Jews round about him, and said unto him, How long dost thou make us to doubt? If thou be the Christ, tell us plainly. Jesus answered them, I told you, and ye believed not: the works that I do in my Father's name, they bear witness of me.
