Acts 3:11-26 Gospel in the Temple

The healing of the man born paralyzed drew a crowd together in the Temple courts which produced the opportunity for Peter to proclaim the Gospel in the heart of  Jewish religious life. This was surely orchestrated by God. 

Peter does his job well by declaring the story of Jesus to be founded upon eye-witness testimony and supported by Scripture. And ofcourse Peter says it as it is, "you guys need to repent". If you do that "revival will happen".
