I could post my picture and bio on my home page, and along with my posts they would tell you a lot about me. And it would be true. But to really know me, you would have to be around me, watch me in action, see how I react to things, and generally put up with me.
If you were thus acquainted with me, you could re-read my posts and my bio and you would understand them in a different way.
You can not help but grow in your understanding of God and of Scripture as a result of living. The experiences of your own circumstance, your maturity as a person, and having observed how God moves in your own life and in the lives of people close to you, unlocks insights that you couldn't possibly have had as a younger person. God is not changing, but you are, and your understanding of him is.
Thats not wrong, its the whole point.
Indeed, everything that you say is true - and we have so much more than a relationship between two mortals for we have the indwelling of the Spirit from the moment we are born again. (John 3)
As Paul describes in I Corinthians 2 - no man can know what another is thinking except the spirit of the man himself, but God has given us the Spirit and thus, we have the mind of Christ. As we surrender, He fills us and leads us and draws us ever near (Romans 8) The Word nourishes us (John 6) and we abide in Him (1 John 4, John 17) allowing the Spirit Himself to bring forth fruit for the Father (John 15).
All very true, Marron. However, those experiences must be backed by the objective facts of Scripture. If we claim there are objective facts of Scripture then we must judge our experiences according to those facts, facts that are immutable themselves.
