What does the Bible say about Christ being the one thing needful?

The Bible highlights the necessity of Christ as the one thing needful for His people. In John 15:5, Jesus declares, 'I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.' This truth is echoed throughout the scriptures, demonstrating that true spiritual growth and acceptance with God can only come through Christ. Without His intervention and grace, we remain powerless and devoid of hope in our spiritual journey.
