"Mr. Gorbachev, tear down this wall!"
These famous words were said by President Ronald Reagan in a speech at the Brandenburg Gate near the Berlin Wall on June 12, 1987. 29 months later the wall was torn down. Interestingly, these famous words were originally written by Peter Robinson, a presidential speech writer. President Reagan liked them and insisted on saying them despite some opposition from other advisors.
Isn’t that what preachers have been doing for millennia? Taking the words of Scripture and repeating them and this produces results in sinners unto their salvation.
