How do we know that the second coming of Christ is true?

The truth of the second coming of Christ is substantiated by multiple prophetic declarations throughout Scripture and the character of God who cannot lie. In 2 Peter 3, Peter reassures believers that just as God has acted in history – from creation to the flood – He will certainly fulfill His promise to return. Moreover, it is through faith that we trust in the promises given in Scripture, as seen in passages emphasizing that God's word stands true and is designed to instill hope in His people (Hebrews 11:13). Believers are encouraged to remain steadfast, awaiting the fulfillment of God's promises.
