The life of Jesus tells you everything you need to know about being a Christian.
Liberal false Christians are spreading nonsense like this on social media to make Christianity look politically correct:
That would have been news to Jesus Himself (the real one, not the one who lives only in the imaginations of cafeteria Christians):
Matthew 4:4 KJV: 4 But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
If everything in the Bible but Christ's earthly ministry were just filler and pull quotes, why would He have said that, and why would the rest of the Bible have been revealed at all?
There's also the minor issue that "killing" and "murder" are not synonymous.
