Envy cripples our ability to examine ourselves.

The story of Cain and Abel when God accepted the offering given to him by Abel and rejected the offering given by Cain, it made Cain very angry.

Envy began to broil in Cain’s heart. The Lord warned Cain of this brooding emotion

Genesis 4:6-7 6 And the Lord said unto Cain, Why art thou wroth? and why is thy countenance fallen? 7 If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
