“Let us consider Genesis 1:2 once again.
While Genesis 1:2 says, ‘And the Spirit of God was hovering over the face of the waters,’ Psalm 104:24 says, ‘O LORD, how manifold are Your works! In wisdom You have made them all. The earth is full of Your possessions–‘ and in Ps. 104:30 we read, ‘You send forth Your Spirit, they are created; And You renew the face of the earth.’
In Job 26:13 we read, ‘By His Spirit He adorned the heavens.’
These texts (and there are others) outside of Genesis echo it and further explain it to and for us. These are instances of inner-biblical exegesis within the Old Testament.
When the Bible exegetes the Bible, therefore, we have an infallible interpretation because of the divine author of Scripture.
Scripture not only records the acts of God, it also interprets them. If we are going to explain the acts of God in creation, God’s initial economy, with any hope of accurately accounting for those acts, we must first know something of the triune God who acts.
And the only written source of infallible knowledge of the triune God who acts is the Bible and the Bible alone.”
