How do we know the doctrine of God's blessing is true?

The truth of God's blessing upon our labor is reflected in the Scriptures, particularly in stories illustrating divine intervention following human effort. For instance, in Matthew 7, the parable of the wise and foolish builders demonstrates that labor without a solid foundation results in destruction, reaffirming that our works must align with God's will. Additionally, in Psalm 127, it states, 'Except the Lord build the house, they labor in vain that build it.' This underscores that God’s blessing is essential for any labor to bear fruit, and therefore reassures us of His faithfulness in the outcomes of our efforts when aligned with His will.
