How do we know that God loves and redeems His people?

In scripture, God's love is intricately tied to His act of redemption. Isaiah 43:1 explicitly states, 'I have redeemed you,' indicating not a mere possibility of redemption but a completed act on behalf of those He has chosen. This echoes the New Testament affirmation that Christ’s death was an actual payment for sin, providing hope for His people. Furthermore, He calls His redeemed ones by name, recognizing them not just as numbers but as cherished individuals in His family, thereby affirming His love and personal investment in their lives.
