John 16:22-24

And ye therefore now have sorrow: but I will see you again, and your heart shall rejoice, and your joy no one taketh away from you. And in that day ye shall ask me no question. Verily, verily, I say unto you, If ye shall ask anything of the Father, he will give it you in my name. Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be made full.
