How do we know that God's promises will be fulfilled?

In 2 Peter 3:9, we see the assurance that "the Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance." This reflects God's character of faithfulness and His sovereign purpose in delaying judgment. The fulfillment of God's promises is rooted in His nature, which is eternally trustworthy. This means that believers can rest assured that the Lord will accomplish all that He has decreed, including His promises regarding salvation and judgment. Thus, we wait expectantly, being reminded that God's timeline is not like ours, but is perfectly orchestrated for His purposes.
