My husband gave me a great analogy when we were discussing an aspect of the Word this morning. Compare the knowledge of God to the knowledge of baseball. Each little rule of baseball doesn't make it baseball. It is the the overall description that defines baseball and each little part of the game makes up the whole.
When I talk to people about God's Word and someone says something I don't understand, I have to look at what I know about God from the whole Word and see if it fits. We don't know everything in the Bible but even after a short time looking at God's word we get the idea of God's concept of love.
Politicians are great examples of isolating just what they want you to believe. Just check out the current election cycle. Sound bites can be an example of downright lying. We sure would not want to do this for God.
In my blog on Context and Forgiveness (context) I wrote about the context of forgiveness in Matt 18. There are many other examples of godly concepts being taken out of context. The reason why God says something where he says it is pretty important. When people take a verse and laud it to the sky to prove a point, check the context. They may be right, but they might be very wrong. Whole denominations have evolved using verse points. Remember chapters and verse numbers were added to the Bible by men.
God is the leading authority of Himself. We are the leading authority on ourselves. It is our choice to take Him at His word in His context.
