The arrogance of human intelligence will blind anyone who thinks they know more than God!
Perhaps we have too low a view of what is happening when a man is blessed of God to preach and teach exactly what we need when we need it.
Even if all men had the desire to be saved (which we know that fallen, depraved man does not), he does not have the ability to move toward Christ. Salvation begins and ends in the will and power of God.
The miracles of Jesus were not for His fame or glory. They were an undeniable testimony that He was the true Messiah!
To say that the miracles of the Bible are just fictional stories and not necessary is to to deny the most needed miracle of all, SALVATION!
