There is no other way to answer this question than to understand that we have a responsibility to care for one another. That is the requirement of God from us. The doctrines of Jesus Christ to the church teaches us to bear one another's burden. We are to be doers of good. Our family is the family of God and the family of God, is a family of love.
The doctrine of love is that of taking responsibility for each other. The Bible says that we should not only mind what belongs to us. We should be mindful of the things of others. We should care for others. When we show our care and love for one another, we are the true disciples of Jesus Christ. A disciple of Jesus Christ is someone who loves others. The doctrines of Jesus Christ teaches us to love one another.
Money is one of the things which we are to share with others. We are to share our money with those who have needs. We are financially responsible for others. We have an obligation to show concern for others. We should do that with true love in our hearts. We should respond with to others not minding without they are related to us or not.
It shouldn't always be about ourselves. One of the reasons we are helped by God is to help others
