How do we know God's merciful kindness is true?

The truth of God's merciful kindness is firmly rooted in the scriptures that testify to His unchanging nature. In Jeremiah 31:3, the Lord affirms His everlasting love, indicating that if He loves you now, He always has and always will. This eternal aspect of His kindness is linked with His decision to be merciful to whom He will, as expressed in Exodus 33:19. The overwhelming nature of His grace is not based on our works but solely on His divine purpose, evidenced in His dealings with Israel and His grace manifested in Christ.
