Being two persons is not real.  Being someone else is not real.  The essence of not being real is to have a divided heart.  To unite the whole person around God by driving out all idols is to unite the personality and to become real.  This is the core of sincerity.  To live in humility before God is reality and to be real.  To live in pride and arrogance is false reality.  Being real is the great need of every Christian.  When it does not happen, it is a turn-off.  When it happens, it is winsome evangelism.

“Teach me Your way, O LORD; I will walk in Your truth; Unite my heart to fear Your name.  I will give thanks to You, O Lord my God, with all my heart, And will glorify Your name forever.” Psalm 86:11-12 (NASB)
