Have I been with you so long, and yet you have not known Me? John 14:9
Philip asked for Jesus to show them the Father. After a discussion of death, and denial and departing, (in John 13) Philip needed a little reassurance from Christ. Just show us the Father. Give us some proof that this is the real deal.
We've talked about doubt and unbelief as we've looked at Jesus' questions. Philip taps into another issue that plagues us as believers- the stall tactic. Just a few chapters back, Jesus plainly says He and the Father are one. Philip knew this. But knowing it, grasping it, required action, and Philip was NOT ready for that just yet. So he stalled.
I have already answered that question
There is no more truth. There are no more answers. Jesus Christ is God, complete and undiluted. The Creator God of Genesis? Jesus. The thundering God on Sinai? Jesus. The God of wrath and judgment the prophets warned of? Jesus. The Savior and Redeemer? Jesus.
There's work to do
Jesus then follows the questions with a mind-blowing statement. You will do greater (more) works than I did. You guys are going to carry this message all over, to far more people than I got a chance to talk to in My 3 years. My earthly face-to-face ministry is ending. The rest depends on you.
You have all you need
Jesus assures them that anything they need to accomplish this mission is available to them through prayer. In addition, the Holy Spirit (Jesus again) will not just with us, but IN us.
No more stalling.
