Though we serve an omnipotent God, there are actually a few things the Bible tells us He cannot do. He cannot lie, He cannot tolerate evil, and He cannot deny Himself. What that means is it is actually possible to contend with God and "win". Now, I know how that sounds, don't dismiss me just yet. What I mean is, if God provided the scenario (sort of like He did with Moses in Exodus 32:9-14), you could actually reason with Him.
I want you to imagine you spoke with God. He sees the evil of today's world, and says to you "the sin of this world is so great, I would be quite within my rights to destroy it with a global flood". You could actually say to Him "but Lord, your word says 'Thus I establish My covenant with you: Never again shall all flesh be cut off by the waters of the flood; never again shall there be a flood to destroy the earth.'" With that one Scriptural quote, the Lord would be convinced (not that He'd need convincing) to relent of His desire to send the second flood.
Quoting Scripture is easy, but sadly, so is twisting it. Sometimes, we do this deliberately, but sometimes, it's just a human flaw. One way to solidify our interpretation is to imagine ourselves discussing it with God. He, after all, is infallible, and more importantly, authoritative. We cannot claim what He does not promise, even if we quote Scripture. Nor can we sustain a false doctrine, even if we quote Scripture. It's His book, and He knows what's in it. Therefore, you will get away with far less in a discussion with God than you could with any human being, even if He went easy on you.
For many of us, this is problematic. Many of us have our favorite verses, but what would happen if we took them to God and said "your word says...". Would He interpret them the same way we do? The only thing more terrifying than the number of people who would have to answer no is that we, ourselves, could very well be among them. Let us do our best to ensure that we are not.
