Something to think about.
14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth. John 1:14
The operative word in this verse is we. John is testifying to what he and his associates have seen. He is testifying to the life of Christ and is speaking as a representative of others that have seen the same thing, a spokesman. We often take the witnesses of Christ to lightly. There aren’t any other witnesses to any ancient historical event as well documented as the life of Christ. These are real people testifying to real events that occurred that have changed the course of history. We should rely on the testimony of biblical witnesses and not on the conjecture of man.
