John 14:20 – In that day you will know that I am in my Father, and you in me, and I in you.
This verse sums up what’s new about Christianity and makes it different from the ways God previously related to mankind. As Christian believers, God does a miracle in is. He causes us to “know” that Jesus is in the Father, we are in Him, and He is in us.
The fact that Jesus is in God the Father reminds us that He makes all things well in our relationship with God. Without Jesus, we don’t have a relationship with the Father. This has been a consistent theme in this book of John. Even though this is consistent, many attempt to read something else into it. The Bible should not be changed to fit ideas that come from outside of it. It must be allowed to speak to us and change what we think. That is the only way we will be able to come to a knowledge of the truth that it speaks. Because of this we need to recognize that it is only Jesus that makes us right with the Father.
As Christians, God also causes us to “know” that we are in Jesus. Jesus is now preparing a place for us in His Father’s house. We are also there because we know that we are in Jesus. Wherever Jesus is, we are also with Him. In a sense, we are already in Heaven because we are in Jesus right now. Although I don’t believe I can adequately explain this, I like trying. I fail to fully understand but I love to think about this fact and what it means. Someday we will fully understand what we now “know.”
Finally, we also “know” that Jesus is in us. Wherever we are, Jesus is also there. In that sense, Jesus is still on earth inside of us. When we submit to His life within us, we are able to do the works He does. We can live with power over sin, not by trying to impress God, but letting the Holy Spirit work in His power through us. We can’t impress God by our own strength, but by Jesus in us we can live like He did.
