A preaching that awakens,
a preaching that enlightens –
as when a light turned on
awakens and of course annoys a sleeper –
that is the preaching of Christ, calling:
Wake up! Be converted!
That is the church’s authentic preaching.
Naturally, such preaching must meet conflict,
must spoil what is miscalled prestige,
must be persecuted.
It cannot get along with the powers of darkness and sin
