1st John Chapter 5
6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
In this format the trinity is easy to accept. We all have a self, a word and a spirit. And by His Word the heavens and earth were created. The Father obviously has a Word and He obviously has a Spirit. And it is self evident that these are one and the same person. But who can give flesh to his word? Our words are as nothing. They have no physical presence. However, they can do great and terrible things. They can lift people up and they can destroy people. God was able to give His Word a body of flesh that we could see and touch. And that body of flesh spoke the Word, that we might know God. Praise God!
