Jonathan Goforth was becoming overwhelmed with the load of work he had to bear and decided to trust God’s promise to supply their every need, and so, with his wife he took the need to God in prayer. Two days later, as unexpected as "rain falling from a clear sky," God perfectly met their need by using an unlikely man.
Mr. Doong was a disheveled, sickly, uneducated man. Yet after meeting Jesus he was so transformed that Rosalind Goforth hardly recognized him, and she never imagined how powerfully God would use the man. Truly God had chosen the humble to shame the wise.
