In all of Jesus' teachings there is noticeable the insistence of that mystic unity of the Father and the Son: "I am in the Father and the Father is in Me." And that for which the Father sent Him was solely to show all men the way back unto the Father, and at the same time that He, Christ Jesus, might be in each of us the way, the truth and the life, preparing us for the day when He might lead us into knowing the Father even as He knew Him. "At that day ye shall know that I am in the Father, and ye in Me, and I in you."
We have shown you in previous articles that only through Love can you come to know Christ Jesus, our Blessed Lord and Master; and we now say that He is the actual expression, the perfect manifestation of the Father's Love in Man. He veritably is the God-Seed planted by the Father in humanity, and is the Light which dwelleth in the darkness. But that Light—God's Love—must be lit in your heart, before you can see and know Christ Jesus there. With the lighting of that Light, then He within you leads you unto the Father, and in time you truly know that He is in the Father, and you are in Him, and He is in you.
From this you must realize that there is a deep mystical meaning of His being in the Father, of we being in Him, and He in us, and we will try to help you get a glimpse of that meaning. The fullness of knowing can only be gained—note this carefully—by going within where He is, where we may know our oneness with Him, and with the Father. And that each one must learn to do for himself.
