The sermon explores the concept of complete surrender to God, drawing inspiration from the life and song of Judson Van Deventer, who composed 'I Surrender All' after wrestling with a calling to ministry. It emphasizes that true surrender involves not only a desire to serve but also a willingness to be shaped by God's grace, aligning with biblical teachings on priesthood and recognizing the importance of both personal devotion and outward affirmation for men aspiring to be pastors. Ultimately, the message encourages listeners to embrace a life of service to God in view of his many mercies.
