It has always been my ambition to preach the gospel where Christ was not known, so that I would not be building on someone else’s foundation. Romans 15:20
Instead of building on someone else’s foundation, preach the Gospel where Christ has not been known yet. There are always people, communities and areas like that. The harvest is always plentiful. Do not ‘ease’ your ministry by ministering where there is already someone’s foundation. That may not be the place where you may experience God at work in you and through you.
