Each convert you make means more revenue, but where is the advantage to the convert?

The Catholic Answers

If the new convert did contribute to the support of his religion that would already be an advantage to him, if Christ rightly commended the poor widow who gave her mite to the Temple. But even if a convert could give nothing he would be none the less welcome. The Catholic Church never wants anyone for what he will bring to her, but for what she can give to him—absolution for his sins, Christ as his Saviour and Guest of his heart in Holy Communion, relief after his death, and heaven in the end. It is all very much to the advantage of the convert.
