Those who make a sustained and conscious effort to improve their thoughts, feelings, actions and habits in accordance with Cosmic Universal Law shall be very glad to have done so. Biblically speaking (Psalms1: 2-3), "blessed is the man whose delight is in the Law of the Lord" (Cosmic Universal Law of the Creator). Though religious taboos may reflect some of this, Jesus tried to teach us that one cannot be blindly rigid and fulfill the Spirit of this Law. One must think deeply and in more complex ways than simply abiding by religious "shalt nots".
Look at the parable of the Good Samaritan as a prime example:
Here, we learn that we must think in a spiritual way that surpasses ordinary religious rules if we are to become more spiritually evolved. Those of us who do not learn to recognize and apply God's Cosmic Laws shall have a 'long hard row to hoe'.
