John 16:22-27 So with you: Now is your time of grief, but I will see you again and you will rejoice, and no one will take away your joy. 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. Until now you have not asked for anything in my name. Ask and you will receive, and your joy will be complete. “Though I have been speaking figuratively, a time is coming when I will no longer use this kind of language but will tell you plainly about my Father. In that day you will ask in my name. I am not saying that I will ask the Father on your behalf. No, the Father himself loves you because you have loved me and have believed that I came from God.
Jesus said that no one would take away your joy, so the only way we can loose our joy if we give it away behind issues of this world.
Jesus is talking about a new relationship between the believer and God. Previously, people approached God through priests. After Jesus resurrection, any believer could approach God directly. A new day has dawned and now all believers are priests. Talking with God personally and directly (see Hebrews 10:19-23). We approach God, not because of our own merit, but because Jesus, our great high priest, has made us acceptable to God.
