That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we unto you, that your joy may be full.
1 John 1:1-4 KJV
Jesus came to Earth and spoke concerning the Kingdom of God, the Kingdom of Heaven.
He uttered secret things, things hidden from the foundation of the World.
He spoke in metaphors, parables, so that the masses might not hear, yet hearing not receive.
He, the Teacher, taught to not be understood? He was the perfect one, who knew that all righteousness and perfection must be fulfilled, perfectly.
