For no reason at all.

Not because of the holidays. Not because you hope to get something in return. Not because it looks good on a resume. Not because you need community service hours. Not because you want to impress other people on social media.   

Do something good for someone for no real reason at all. 

Do it because you follow Jesus, and doing something good for others is a significant part of your identity. You love Jesus, and the result is that you love others with no strings attached.
