How can one ensure that their work is done for God and not for man?

To ensure that one's work is done for God and not for man, it is important to have a sincere and humble heart, seeking to honor God in all actions and decisions. This can be achieved by regularly seeking guidance through prayer, studying and applying biblical principles, and prioritizing serving others with love and integrity. By keeping a focus on pleasing God rather than seeking approval or recognition from others, one can align their work with God's will and purpose.
