God wants to display his love for His people! At the end of the gospels Jesus gives the “great commission”, He instructs his followers to “go into all the world and preach the gospel”,
he then says “these signs shall follow them that believe in my name, they shall cast out demons, they shall raise thee dead”…etc we see that in the great commission it is 80% miracles and only 20% preaching. We also see that in Jesus’s ministry that miracles are the gospel message and that the gospel message should be a explanation of the miracles. Why would we stop God from showing off His Power?
