Because most people who lend money to people in need are richer, more generous, more kind, or more trusting. With these good qualities, these people are likely to have a brighter future.
People live all their lives, walk around, borrow money everywhere, and other things are similar. For example, it may be human nature not to help others when they are in trouble. However, it is also a blessing to help others as much as possible.
Because I don't know when I need someone's help. Somehow, it may not be the person you helped directly, so I will return your help to you. Maybe someone he helped, or someone else, helped you.
Moreover, if you send roses, there will be more fragrance on your hands. Blessed are those who can always help others. But in any case, if everyone is grateful and sends as many roses as possible, the world will always be better.
