Sometimes I think that we forget that the Scriptures are infallible, inerrant and authoritative but our understanding of the Scriptures is not. If we assume that we understand Scriptures correctly in things that the Scripture is not clear on we will be in danger of making something authoritative that is just simply our opinion and not actually the Word of God. Worse yet, we sometimes try to make our opinion the standard by which others are bound because we have mis-equated the Word of God for our words about the Word of God.
We must caution ourselves against this with at least three cautions.
1. The caution of humility. - We must always approach God's Word humbly.
2. The caution of study - We must always study hard and allow God's Word to speak for itself, not proof-text our way through the Bible.
3. The caution of community - our interpretation should not stand alone against the history of biblical interpretation or even in the midst of our own contemporary community. If you think it means something that no one else thinks it means you should probably be overly cautious and study extra hard!
