Thomas a Kempis emphasizes that God must be the ultimate purpose of our lives to attain true blessing. He warns against the dangers of self-seeking and encourages believers to refer all things back to God, the source of all goodness. Acknowledging God as the giver of all gifts leads to a heart filled with grace, while seeking glory apart from Him results in distress. True joy and virtue come from recognizing that all good is from God, and we must return thanks to Him. Ultimately, divine love is the key to overcoming self-love and envy, leading to a life of true wisdom and joy in God alone.
