DISBELIEVING...Not "Doubting" Thomas

He's often referred to as "Doubting Thomas." But when he told his fellow apostles that unless certain conditions that he laid down were met, he REFUSED to believe that Christ was risen from the dead. A better name at that juncture would be "disbelieving Thomas".
He pictures many a child of God who go beyond doubting some truth or promise is God's Word where...for all intents and purposes...they deny it, unless they have clear evidences (which they have established) that it's true. This is when a Christian starts walking by sight instead of by faith.
