This sermon provides a detailed exposition of Chapter 29 from the Baptist Confession of Faith, arguing exclusively for believer's baptism by immersion. The speaker outlines four key aspects of the ordinance: its nature as a New Covenant dominical sign, its proper recipients who must profess faith, the necessity of water and the Trinitarian formula, and the mode of full immersion. Drawing on covenant theology, federal headship, and the clarity of New Testament revelation, the text refutes infant baptism by emphasizing that only those united to Christ by faith can rightly receive this sign. The presentation maintains a scholarly and instructional tone, aiming to clarify Reformed Baptist distinctives against Paedo-Baptist traditions.
