How do we know that mercy is central to God's relationship with us?

The psalmist cries out for God's mercy to be upon us according to our hope in Him. This reflects a profound theological truth: the Lord meets us based on our reliance on His mercy. In a sovereign grace framework, we understand that our salvation and relationship with God rest entirely on His mercy rather than our works or efforts. The certainty of God's mercy is linked to the confident expectation we place in Him, emphasizing the importance for believers to weigh their hope entirely on the grace of God.
