I think Jesus covered this in the parable of the sower:

And the ones sown among the thorns are others who hear the Word;
Then the cares and anxieties of the world and distractions of the age, and the pleasure and delight and false glamour and deceitfulness of riches, and the craving and passionate desire for other things creep in and choke and suffocate the Word, and it becomes fruitless.
And those sown on the good (well-adapted) soil are the ones who hear the Word and receive and accept and welcome it and bear fruit—some thirty times as much as was sown, some sixty times as much, and some [even] a hundred times as much.
