Resistance to believing...

Did you know that resistance to believing can be a sign of a hardened heart? 

Jesus pointed out the wickedness of such a heart condition.  Matt 12:38-39 (NIV) 38Then some of the Pharisees and teachers of the law said to him, “Teacher, we want to see a miraculous sign from you.” 39He answered, “A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah.   

The Pharisees and teachers of the Law seemed to request for some reasonable proof of Jesus' authority as God's representative.  Prove you are from God by demonstrating God's power. Why then did Jesus come out so strongly against this simple request? After all, Jesus was already demonstrating God's power - healing the sick, casting out demons, raising the dead!  Because their request came from a hardened heart.  They were not seeking for God but seeking to put obstacles against believing.  Hardened hearts do not want to believe but to disbelief.  But the Pharisees did not seek the truth about Jesus.  Only for reasons to disprove Jesus.  

Those with a genuine seeking heart will not set conditions for believing but is open to examine whatever evidence God provides.
