Whom to Fear; Whom Not to Fear      

   Acting as if we are what we are not. That's hypocrisy.

   Acting publicly as godly while hiding immorality, greed, lust etc. - hypocrisy, living a lie. Think, Pharisees. And from time to time, most all of us.

   Jesus told a large crowd that no one gets away with it. 

   There is nothing concealed that will not be disclosed, or hidden that will not be made known. - Luke 12:2  NIV 

   I tell you, my friends, do not be afraid of those who kill the body and after that can do no more. ... Fear him who, after killing the body, has power to throw you into hell. 

   He tells them/us that He sees all his creatures, yet we are worth more to him than many sparrows. He even numbers the hairs on our head. In other words, the Lord knows us inside and out. Everything. He wants us everyone to know him:

   I tell you, whoever acknowledges me before men, the Son of Man will also acknowledge him before the angels of God. But he who disowns me before men will be disowned before the angels of God. 

   Then, Jesus makes a remarkable statement, well before his Last Supper discourse and Pentecost, 50 days later:

   And everyone who speaks a word against the Son of Man will be forgiven, but anyone who blasphemes against the Holy Spirit will not be forgiven. (Also in Matthew 12.) 

   Blasphemy: The deliberate rejection of the Holy Spirit's witness to Christ, his Word and his convicting work against sin. The voice of the Spirit alone leads us to forgiveness. Grieving, resisting the Spirit leads to hardening of heart, which leads to depravity, and at God's determination, the Spirit ceases to lead one to repentance. (From Bible commentary.)
