Have you ever told a lie to G-d? Have you told Him you did something for one reason or another but really you had a different motive for doing it? Remember, G-d knows the heart. He knows your innermost thoughts. Just like a parent knows the child, G-d knows you even more. And know this, the Scriptures teach us that those who worship the L-rd must worship Him in spirit and truth. Are you being honest with G-d?
"God is spirit, and those who worship Him must worship in spirit and truth." John 4:24
