There are three conversions necessary (for the Christian life): the conversion of the heart, the mind, and the purse.
People go through three conversions: The conversion of their head, their heart, and their pocketbook. Unfortunately, not all at the same time.

It has long been observed, that an atheist has no just reason for endeavouring conversions; and yet none harass those minds which they can influence, with more importunity of solicitation to adopt their opinions.

Don’t optimize for conversions, optimize for revenue.
