There are layers of truth. In sowing and reaping you receive according to what you have done. But there is a higher law, the law of blessing in which you receive according to what He has done, not what you have done.
Our life in Christ starts in experience. But we have a culture that values information and theology. Theology is not bad, but it is to give us legal access into encounters and transformation. What you know can keep you from what you need to know if you don't maintain a child's heart.
