How do we know God's love is steadfast?

Moses's plea in Psalm 90 to 'satisfy us in the morning with your steadfast love' reveals a deep trust in God's unchanging nature. The psalm illustrates how, despite the afflictions and brevity of human life, God's love remains a source of joy and strength. His love is likened to a daily renewal, emphasizing that it is through God's unfailing love that we find true satisfaction and gladness. This reflects the Reformed understanding of God's grace, which upholds that His love is not conditional upon our performance but is constant and reliable.
