This sermon explores the tension between God’s sovereignty and human free will in John 12:37–43, where some reject Jesus despite witnessing His miracles while others believe only partially. Pastor Mike emphasizes that the mystery of why some believe and others do not cannot be fully explained—it rests in God’s divine purpose beyond human understanding. Ultimately, he invites listeners to embrace both God’s sovereignty and their responsibility to respond with wholehearted faith, trusting that salvation comes from God’s grace alone.
