How do we know the promise of Christ's return is true?

The certainty of Christ's return is affirmed throughout scripture, particularly in 2 Peter 3:3-7, where Peter warns against scoffers who question this promise. He points to the historical acts of God, such as creation and the flood, demonstrating God's sovereign control over the world. The faithfulness of God in fulfilling His promises in the past serves as a basis for trusting in His future promises, including the return of Christ. Peter reinforces that God's timing may differ from human expectations, but it is based on His perfect plan.
