What does the Bible say about God's grace and love?

The Bible portrays God's grace as fundamentally unconditional, rooted in His character and the covenant of grace established before the foundation of the world. This is vividly illustrated in the book of Hosea, where God instructs the prophet to love his unfaithful wife, Gomer, which serves as a parallel to God's relationship with His chosen people. Despite their unworthiness, God's love is steadfast and eternal, showing that salvation is conditioned solely on Christ's righteousness rather than any merit of our own.
