The sermon centers on the transformative reality of eternal life found solely in Jesus Christ, emphasizing that true belief is not merely intellectual assent but a committed, ongoing relationship with Him as Lord and Savior. Drawing from 1 John 5:11 –13, it underscores that eternal life is a gift from God, not earned, and is inseparable from having the Son—those who possess Him have life, while those who do not are without it. The preacher uses the metaphor of marriage to illustrate that faith involves a definitive, lifelong commitment, not perfection, but a heart that trusts and surrenders to Christ's authority and grace. He challenges listeners to examine whether they are merely acknowledging Christ's truth or actively receiving Him as Lord, warning that rejecting His record is equivalent to calling God a liar. The tone is both urgent and pastoral, calling for personal, heartfelt response to the gospel with clarity, conviction, and hope.
