Integrity is choosing your thoughts and actions based on values rather than personal gain. You need integrity to STAY in God. Because whatever you do for your personal gain will KEEP you in pride not in CHRIST.
This is how it is. You do all things to serve others and gain positive karma. Avoid gossip and hateful thoughts, for that creates negative karma. In all you do, do it for good, and do it so it will help and serve others.
