John Wesley preaches on the concept of being 'Almost Christian,' emphasizing that many people live morally upright lives and follow the external forms of Christianity without truly embracing the faith. He distinguishes between mere outward compliance with Christian principles and the deeper, transformative love for God and neighbor that defines a true Christian. Wesley warns that being almost a Christian is insufficient for salvation, as it lacks the sincerity and genuine faith that leads to a heartfelt relationship with God. He calls for self-examination and urges listeners to seek a complete commitment to Christ, characterized by love and faith. Ultimately, Wesley encourages believers to strive for a full and authentic Christian life, filled with the love of God and a sincere desire to serve Him.
