Theology affects my Bible reading. When I remember God loves me, I can take even words of correction as loving. When I forget God’s love, I find it hard to accept God’s correction.
In other words, if I believe God loves me, I can accept God’s word as loving, even when it seems unpleasant. If I believe God is out to get me, even words of love can be twisted into something like a personal attack.
My theology (do I view God as loving or adversarial?) makes a big difference in being able to hear God.
