If Christ is not your foundation, you don’t have a foundation. You will fall, and it will hurt. I know because I’ve tried. Trust in Him to be a strong foundation. Not yourself and not anything outside of Him. Trust in Christ alone.
The Bible says to love your neighbor, not to fix your neighbor or to save your neighbor. It’s only Jesus who can save. Just love and keep loving the people around you. That’s how the world will change.
