Does the Errancy of Fundamentalism Disprove the God of the Bible?

John 10:10 writes:1. Since the Christian God exists, there is a Being who is omnipotent, omniscient, and perfectly good.2. Since there is a Being who is omnipotent, omniscient, and perfectly good, His revelation as revealed in the Bible is error-free, unambiguously clear, and objectively verifiable as true in all matters essential to having an eternal life relationship with the Christian God.3. In Him, you also, after listening to the message of truth, the gospel of your salvation--having also believed, you were sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance, with a view to the redemption of God's own possession, to the praise of His glory. (Eph 1:13-14)
