My feelings are important for many things. They are essential and valuable. They keep me aware of much that is true and real. But they tell me next to nothing about God or my relation to God. My security comes from who God is, not from how I feel. Discipleship is a decision to live by what I know about God, not by what I feel about him or myself or my neighbors. ‘As the mountains are round about Jerusalem, so the Lord is round about his people.’ The image that announces the dependable, unchanging, safe, secure existence of God’s people comes from geology, not psychology.
