This phrase is usually used in an inappropriate manner. I am not sure why it has come to be used this way but in the Bible this phrase is a powerful reminder of why a Christian should do whatever he does – and that is “for Christ’s sake.”
Ephesians 4:32 – And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
Paul closes out the chapter on “unity” by reminding us of our highest motive and that is “for Christ’s sake.”
The only way that God could forgive you and I for our gross sins was “for Christ’s sake.” If God could forgive us, love us, and be tenderhearted toward us for Christ’s sake couldn’t you and I humble ourselves and do the same toward our brethren. Unity starts by looking to Jesus and then imitating His example.
Forgive today, be kind today, be a tenderhearted Christian today – For Christ’s Sake.
