love is not blind (Phil 1:9)

Philippians 1:9

And it is my prayer that your love may abound more and more, with knowledge and all discernment

Paul wouldn't recognise the attitude that can sometimes exist today that says "I love God, He loves me, and that's all that matters" and avoids any further "theology" than that. Loving God is tied up in knowing Him. Without growing knowledge of his character and actions on our behalf, then we wont be growing in our love for Him, or we're growing in our love for a self-made "god". The more we know Him, the more we love Him. They feed each other. I want to know everything about my wife because I love her, and the depth of knowledge fuels that love.

With love and knowledge is discernment - the more we know of how God has revelaed himself, the more we will be able to discern the real thing, the truth from the lies. The more we love Him, the more we'll want to discern the real thing, because we only want the truth.
