How do we know that hope is true in Christianity?

Our hope is anchored in the resurrection of Jesus Christ, which serves as the pivotal proof that God is faithful to His promises. As Paul states in Romans 4:25, Jesus was raised for our justification, affirming that God’s righteousness is imputed to those who believe. This certainty allows Christians to trust in God's promises, knowing that His faithfulness and power will sustain us until the end. A living hope involves both a present faith and a future assurance that Christ will fulfill what He has promised.
