The sermons keep getting better! I have listened to 4 recent sermons from this broadcaster and each one is better than the last. This man's congregation is being served a hearty meal each week. The four fold organization of the fruit, ultimate godliness, ultimate blessedness, ultimate freedom and ultimate law-keeping is extremely insightful plus it is easily remembered.
Abraham declared his imputed rightousness Thinking of Jesus' substitutionary death as a baptism into fire is helpful.
How the old covenant relates to the new is a difficult topic. Our Presbyterian brothers see more continuity between old and new than you. I know you know that. Why Presbyterians baptize children of believers is easily understandable. Hopefully your listeners understand that Presbyterians have ample Biblical grounds for applying the N.T. covenant sign and seal to their children.
Great Sermon! The five fold baptism is a very interesting insight. Also the concept of baptism as a mural is helpful. I've read Doug Moo's commentary on Romans 6. He has a different interpretation than Pastor Reuther's and John Murray's in his commentary.
