What about quantity?
Typically, missionaries (and churches) track the number of “decisions” made by the people with whom they shared the gospel. Practically, this translates into counting how many people “prayed to receive Christ.”

Listening? –– Are people paying attention?
If we share the gospel in a culturally meaningful way, our message will not come across “abstract” or unrelated to daily life. We cannot change people’s hearts; however, we can convey the truth in a manner that makes sense. In this way, we expect more people to pay more attention to us than they otherwise typically do.
Longevity? –– How does attrition affect churches?
When the gospel truly changes people’s hearts, it fosters a new manner of life. There is greater perseverance in genuine faith that in superficial, religious belief or in the response that comes because of social pressure.
