Seek The Savior Not The Signs

One day some teachers of religious law and Pharisees came to Jesus and said, “Teacher, we want you to show us a miraculous sign to prove your authority.” But Jesus replied, “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. For as Jonah was in the belly of the great fish for three days and three nights, so will the Son of Man be in the heart of the earth for three days and three nights. “The people of Nineveh will stand up against this generation on judgment day and condemn it, for they repented of their sins at the preaching of Jonah. Now someone greater than Jonah is here—but you refuse to repent. The queen of Sheba will also stand up against this generation on judgment day and condemn it, for she came from a distant land to hear the wisdom of Solomon. Now someone greater than Solomon is here—but you refuse to listen. “When an evil spirit leaves a person, it goes into the desert, seeking rest but finding none. Then it says, ‘I will return to the person I came from.’ So it returns and finds its former home empty, swept, and in order. Then the spirit finds seven other spirits more evil than itself, and they all enter the person and live there. And so that person is worse off than before. That will be the experience of this evil generation.” (Matthew 12:38-45 NLT)

The greatest miracle in all the world was when Jesus rose from the dead. Nothing is even close second. His resurrection is the exclamation point at the end of the sentence. The empty tomb is evidence enough of God's power. We must seek the savior not the signs.
Furthermore, we must allow Jesus to occupy the empty space of our spirit or we will let it be occupied by demonic things. It isn't good enough that Jesus heals a body only if, indeed, we don't ask Him to reside in our spirit as Lord. Often, people want what Jesus can do for them (physically, materially) yet they reject His being Lord of their lives. Nothing more than a temporary experience if He isn't asked to stay!
