Grasping the Grace, Hitting the Heart
What touched me most in attending the preaching training on the book of John is that our expository sermons should grasp the grace of our Lord. He is the Lord of grace and cares not for our worship, unless we worship in spirit. We must interpret and grasp grace more profoundly.
In John, we see that Jesus attends a wedding, happy and excited, abundantly providing wine to people, bringing us a lot of comfort and joy. Jesus also publicly, radically takes on the work of cleansing [the temple.] The same Lord stands behind both events. If Jesus breaks into our lives, on the one hand providing food and on the other hand turning over tables, these direct images reveal to us his authority.
