John Gill emphasizes the importance of understanding God's perspective on time in his sermon on 2 Peter 3:8. He reassures believers that the delay in Christ's return should not cause doubt, as God's timing is vastly different from human understanding; a day for the Lord is like a thousand years and vice versa. This perspective encourages the faithful to maintain their hope and expectation for Christ's second coming, regardless of how much time passes. Gill draws on Jewish traditions and interpretations to illustrate that God's promises are not bound by human timelines. Ultimately, he calls the congregation to trust in God's faithfulness and timing.
