For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one (1 John 5:7).
We are still learning at the knee of the Holy Spirit. Here he comes up with another threesome, the last being the water, the blood, and the Holy Spirit, and now we have Father, Word, and Holy Spirit. In heaven, in that perfect place, we find the description of the Trinity, the three expressions of God, or three personalities. The Father speaks the Word, the Holy Spirit inspires the writing of the Word, and Jesus is the incarnation of the Word. So from heaven comes that handbook of spiritual reality, the Word of God. And to what do these three bear witness through their speaking, writing and being? The Truth.
Interesting that Pilate asks Jesus, “What is truth?” when Truth was standing right in front of him. I often have little squabbles with unbelievers who want to tell me how outdated, or wrong the Bible is. I like to ask them if they have read the Bible, because I know they haven’t. When they admit they have not I ask how they can judge a book they haven’t read? It’s amazing how my question always stymies them. They are only quoting what Satan had to say. We, however, have the only true witness: the Father, the Word, and the Holy Spirit.
