First century aspiring Christians didn’t have a written word to rely on—they didn’t have a New Testament—which may have been to their advantage. They didn’t need the written word, for as promised, Jesus sent the Holy Spirit to guide them. The paradox today is that the written word can sometimes be a distraction, getting in the way of someone becoming truly Christian. For as Jesus warned:
“You study the Scriptures diligently because you think that in them you have eternal life. These are the very Scriptures that testify about me, yet you refuse to come to me to have life. … The Spirit gives life; the flesh counts for nothing.” (John 5:39-40 and 6:63)
Oh sure, Jesus relied on scripture when He walked the roads of ancient Israel. But He relied on His Father more. And if we’re going to consider ourselves Christian, Jesus calls us to do the same:
“I will ask the Father, and He will give you another Helper, so that He may be with you forever; the Helper is the Spirit of truth. … But the Helper, the Holy Spirit whom the Father will send in My name, He will teach you all things, and remind you of all that I said to you.” (John 14:16-17, 26)
“I have much more to say to you, more than you can now bear. But when he, the Spirit of truth, comes, he will guide you into all truth.” (John 16:12-13)
