God's covenant is established through His faithfulness, as seen in the eternal covenant sealed by the blood of Jesus Christ.
The truth of God's covenant can be understood through the lens of the everlasting promises contained within Scripture. In Psalm 25:14, we see that God promises to reveal His covenant to those who fear Him. This covenant is a reflection of God’s eternal commitment to those He has chosen. It is sealed through the sacrifice of Jesus Christ on the cross, which signifies the fulfillment of God's promises. As the blood of Jesus is referred to as 'the blood of the everlasting covenant,' it assures believers that God's promises are secure. His faithfulness is unwavering, making His covenant completely trustworthy.
