Matthew 22:37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. [kjv]
ο δε ιησους ειπεν εφη αυτω αγαπησεις κυριον τον θεον σου εν ολη τη καρδια σου και εν ολη τη ψυχη σου και εν ολη τη διανοια σου [gnt]
Someone has
integrity (consistency) if they have
unity of thought, speech, action, and feeling.
That is, there is no contradiction between what they are thinking, what they are saying, what they are doing, and how they are feeling.
Is the
"heart" better described as a
direction or a
location?
This is stated in the
OT (Old Testament) and by Jesus in the
NT (New Testament). Having
integrity in this sense appears to not be sufficient.
