How do we know that God's blessings come from His grace?

In the sermon, it is emphasized that God's blessings do not depend on how diligently or perfectly His people follow Him. Instead, they are rooted in His grace. The blessings that believers experience are tied directly to who God is rather than the believers' abilities or moral standing. For example, a loving father works to provide for his family, and similarly, God, as our heavenly Father, provides all we need through His grace. This understanding affirms that our ability to receive blessings is a gift from God, illustrating His kindness and desire to see His children thrive more than any merit we could claim for ourselves.
