"And he shewed us how he had seen an angel in his house, which stood and said unto him, Send men to Joppa, and call for Simon, whose surname is Peter; Who shall tell thee words, whereby thou and all thy house shall be saved." Acts 11:13-14
Let Scripture speak for itself. The history recorded in Acts is irrefutable--the Gospel message "turned the world upside down" via the preached Word without even the slightest hint that actions communicated the message of the Gospel, and only slightly more so that believer's actions communicated the need for the Gospel (Acts 16). In fact, you will find much more support in the Gospel exhibited through actions as a catalyst to an increased effort to paganize the Gospel message (Acts 14 and 16)
