While the Scriptures teach about miracles, signs and wonders they must be kept in perspective.
The cross must always be foremost because signs and wonders don't change hard hearts.
An overemphasis on the miraculous is a sign of spiritual immaturity.
Luke 10:17 The seventy-two returned with joy and said, 'Lord, even the demons submit to us in your name.'
18 He replied, 'I saw Satan fall like lightning from heaven. 19 I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. 20 However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven.'
