Why does Jesus say their real father is “the devil” 
		(John 8:43)?
		The devil lied to Eve and caused sin and death to enter into the world. 		
		“From the beginning he was a murderer and ... a 
		liar”  (John 8:44), so those who want to murder and lie belong to 
		the devil.
What about telling a white lie?
		Lie has no color. 
To which of the people who rejected Him did Jesus cling?
		Jesus implored crowds to believe in Him so that “He 
		who has ears to hear” (Matthew 13:9) can hear and believe. Jesus 
		clung to no one but God the Father and certainly not to anyone who 
		rejected Him. He preached the Gospel with full confidence that
		“He who is of God” will hear
		“God’s words” (John 8:46) and believe in Him, 
		while those who “are not of God” (John 8:46) 
		won't.
How do Jesus' words and example impact Gospel 
		preaching and witnessing today?
		It frees us to focus on sharing the Gospel accurately and in its 
		entirety, including sin, hell, repentance, and leave who does and 
		doesn't believe entirely up to God.
What does that mean for the myriad modern techniques 
		and strategies aimed at getting unbelievers to say a prayer, which 
		supposedly will turn them into Christians?
		They are unbiblical and often driven by the desire to fill the pews with 
		donors. And a Christian telling an unbeliever that he or she is saved is 
		worse than a doctor telling a man who has curable cancer that he is 
		cancer-free.
