Then Jesus told him, “You believe because you have seen me. Blessed are those who believe without seeing me.”

Do we believe without seeing proof?

Matthew 16:4
Only an evil, adulterous generation would demand a miraculous sign, but the only sign I will give them is the sign of the prophet Jonah.” Then Jesus left them and went away.

Are we seeking after miraculous signs and wonders and the demonstrated physical evidence of measurable results?

Revelation 16:14 ESV
For they are demonic spirits, performing signs, who go abroad to the kings of the whole world, to assemble them for battle on the great day of God the Almighty.

Do we realize that signs and wonders are not necessity evidence of true prophets or of teachers of truth?

Matthew 24:24 ESV
For false christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect.

Shouldn’t we examine the fruit as signs of the motives of those practicing signs and wonders to see if they are living lawlessly, being aware of any evidence that their activity is of Satan?

2 Thessalonians 2:9 ESV
The coming of the lawless one is by the activity of Satan with all power and false signs and wonders,

Can’t we see that seeking the supernatural isn’t necessarily seeking the will of the one true God?

Can’t we see that seeking spiritual things isn’t necessarily seeking a restored relationship with the one true God?

Unity within the body of believers and avoiding the foolish controversies over the traditions and dogma of men is good,  but there is no unity between light and darkness,  there is no unity between truth and lies.

A “Christian” that is not at war against sin, darkness and the evil principalities of this world – can they make their claims by name alone?

“Beware of false prophets who come disguised as harmless sheep but are really vicious wolves.  You can identify them by their fruit, that is, by the way they act. Can you pick grapes from thornbushes, or figs from thistles?  A good tree produces good fruit, and a bad tree produces bad fruit.  A good tree can’t produce bad fruit, and a bad tree can’t produce good fruit.  So every tree that does not produce good fruit is chopped down and thrown into the fire.  Yes, just as you can identify a tree by its fruit, so you can identify people by their actions. “Not everyone who calls out to me, ‘Lord! Lord!’ will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter.  On judgment day many will say to me, ‘Lord! Lord! We prophesied in your name and cast out demons in your name and performed many miracles in your name.’  But I will reply, ‘I never knew you. Get away from me, you who break God’s laws.’
