What's the Promise of John 14?

In that day, you will know I am in the Father. You are in me and I am in you. The Holy Spirit begins to cause his fellowship with the Son to play out in our interior world. When you begin to feel that type of dynamic, spirit life happening on the inside of you, nothing feels impossible anymore. It's under the conduction of the Spirit where you and I receive the grace to leverage authority and breakthrough on behalf of the cosmos.
