Yes, we are financially responsible for others. It is our responsibility to take care of others. We are to practice good doing for one another. We are to look after one another in love and do good to them. The responsibility of helping others financially is upon us as christians. It is what God teaches us.
Christians are people of love. The love of God should proceed out of us. We should show forth this love in every way possible. We should be concerned about others. We should reach out to them in love. We should not be selfish.
Whatever we can do to be a blessing to others, we should do it. Giving our money is one way of blessing the lives of others.
The Bible teaches us to do good to others. We were created to do good. Good work is what will show to the world the love of God that we preach. Let us take responsibility and help others financially.
