You can be so preoccupied with your own interests or problems that you are oblivious to other people’s needs. Think about if Jesus only thought about His feelings. Would Jesus have gone to the cross? (Father let this cup pass from me) We are to be Christ like, denying self requires us to care about others. When you see someone you know, can you tell us about their interests?
Philippians 2:4 (ESV)
4 Let each of you look not only to his own interests, but also to the interests of others.
