The Bible gives us a healthy dose of realism instead. It tells us what we can't do on our own. We are never independent of God, even in rebellion. It's pretty humbling. Here's a list of man's limitations:
- Man cannot direct his own course. "I know, O Lord, that the way of man is not in himself, that it is not in man who walks to direct his steps." (Jeremiah 10:23)
- Man cannot provide for his own needs. "You shall remember the LORD your God, for it is he who gives you power to get wealth" (Deuteronomy 8:18).
- Man cannot know or trust his own heart. The Disney princesses (and Ralph Waldo Emerson) are wrong. "The heart is deceitful above all things and desperately sick: Who can understand it?" (Jeremiah 17:9)
- Man cannot even keep himself alive. "Which of you by being anxious can add a single hour to his span of life?" (Luke 12:25)
