What does the Bible say about human self-sufficiency?

The Scriptures consistently emphasize that human beings are not self-sufficient. Isaiah 55:8-9 states that God's thoughts and ways are infinitely higher than ours, reflecting our limitations and need for divine grace. In John 15:5, Jesus plainly declares, "Without me, you can do nothing," indicating that true strength and accomplishment come solely from being connected to Him. The world's message of self-sufficiency can lead us to ignore our need for reliance on God, thereby fostering spiritual pride and ultimately distancing us from His grace.
