Prayer and works of love
We should pray for ourselves out of inner need, while we should pray for others out of genuine love. The greatest charity that we can offer to a person is to pray for them.
Of course, when we can also help them in practice, we should do it, because otherwise, our prayer will become dry and useless. Therefore, our prayer should be accompanied by works of love when we are capable of doing so.
