How do we know God's mercies are true?

The Apostle Paul refers to the 'mercies of God' as foundational truths that motivate God's people to serve Him. These mercies include God's free and reigning grace, His predestining and justifying purposes, and His calling of sinners into His incredible salvation plan. The mercies of God are not abstract but are directly connected to His actions towards humanity, primarily in Christ. When we comprehend God's sovereignty in our salvation and learn about His favorable disposition towards us, we recognize the truth of His mercies as compelling realities that beckon our gratitude and devotion.
