How do we know that God bestows blessings according to His purpose?

The theological perspective that God's blessings are bestowed according to His purpose is foundational in understanding His sovereignty. In Isaiah, God contrasts human thinking with His divine purpose, illustrating that His thoughts and ways are far superior to ours. Believers are reminded that God's mercy and favor are not dependent on their actions or condition but are rooted in His sovereign will. This truth encourages Christians to trust in God's goodness and plan rather than relying on their own abilities or merit.
