Catchy advertising slogans don’t sell rollerblades to an indifferent world. Spending too much time on catchy Christian slogans and special event talk titles is likewise not worth it. No one goes to your conference this year because of the theme… Like ‘Behold! Your God’ or ‘God’s Mission; God’s World’. Yeah. Not a major persuasion point.
Many things that show the beauty of the rollerblading vision of human flourishing slowly do their work, like a mustard seed slowly growing, for example.
There are a bunch of similar things we Christians can do as well, that contribute towards the work of getting a hearing for the gospel. These pre-evangelistic things prepare the way for gospel conversation and proclamation.
