Under Gods Command
John 16:12-13 “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. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
The truth into which the Holy Spirit guides us is the truth about Christ. The Spirit also helps us, through patient practice, to discern right from wrong.
Jesus said the Holy Spirit would tell them “what is yet to come”- the nature of their mission, the opposition they would face, and the final outcome of their efforts, they didn’t fully understand these promises until the Holy Spirit came after Jesus death and resurrection. Then the Holy Spirit revealed truths to the disciples that they wrote down in the books that now form the New Testament.
