23 In that day you will no longer ask me anything. I tell you the truth, my Father will give you whatever you ask in my name.
24 Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete.
Again Jesus bridges the gap between the Old Testament and the New Testament in that before Jesus people had to pray to the high priest and the high priest would pray to God for them. Now that we have Jesus, we can go to Him directly, presenting ourselves to Him and asking Him anything even down to the smallest request anyone can think of.
