How does God ensure that His promises about the new creation will be fulfilled?

In Revelation 21:5, God commands John to write that His promises are 'true and faithful,' illustrating God's unwavering commitment to His Word. The sermon expounds on how these assurances reflect God's credibility; every promise made in Scripture will come to fruition. This certainty allows believers to rest in the knowledge that God is actively making all things new in their lives and in creation. His declarations, backed by divine authority, assure Christians that no matter their current circumstances, the hope of eternal glory and restoration in the new creation is firmly established, resulting in a confident expectation of the future.
