Traditional religions usually acquire new followers through:
(a) Some good messages for living meaningfully;
(b) With hopes for living even better after death; and
(c) With the energetic dedication of efficient missionaries:
All this is the religious equivalent of having a good product, promises of usefulness of the product, and effective advertisement in business.
A cynic would and can emphasize other factors, like threats, monies, and force: which are also effective ways of spreading religions.
Success in proselytizing calls for use of all these to varying degrees, depending on the target population.
