How do we know God's eternal covenant is true?

The assurance of God's eternal covenant comes from His immutable nature. Hebrews 6:17-18 emphasizes that God’s promises are immutable and are supported by His unbreakable oath. This covenant is not based on human actions or conditions, but rather on God's sovereign will and grace. We find comfort in knowing that it is sealed by the blood of Christ, providing believers with a firm foundation in their faith. The guarantees of God’s covenant encourage believers to trust in His faithfulness throughout all circumstances.
