The use of arbitrary rules are not appropriate when you are attempting to achieve a goal. Rules generally are carefully designed to assist you in reaching the goal. They ensure that you can achieve the goal within the time frame and in the manner required. If you or someone connected to you makes an independent decision to change the rules, you risk not being able to accomplish the plans, goals, and/or purposes.
When the rules have been designed by someone with superior knowledge of the goal, and of the changes and procedures necessary to accomplishing the goal, they should never be arbitrarily supplemented or amended. More importantly, should you detect the slightest amendment in any aspect of the rules, you have an obligation to personally examine the original dispensation of the rules in order to ensure that your pursuit of the goal will not be in vain.
Much has been said about the relationship between the three Abrahamic religions--Islam, Judaism and Christianity. They each have new man-made rules and annotations that render them dramatically different from the original inspired works. However, each believes that their knowledge of God is not only unique, but also supreme. Each of these religions is indeed unique, and each is supreme in its knowledge and understanding of one aspect of the nature of God.
Judaism has a unique and supreme understanding of El Shaddai, whom they refer to as the God of Israel. They know that El Shaddai is the Father of all the universes. They also know that he is the Supreme God, our God Almighty. Islam has a unique and supreme understanding of Elohim, also referred to as El Elohim. Some in Islam know that he is the God of our singular universe. They also know that there are other gods of the billions of other universes.
Christianity has a unique and supreme understanding of Jesus of Nazareth, the Messiah. Many of them know that Jesus was God because he had in him the spirit of El Elohim. They also know that he is the only source of forgiveness for the sins that all men and women have committed. He is the Messiah who must return in order to redeem the earth from the reign of sin and death.
When the Messiah returns, he will return not only to the three religious groups that claim Abraham as their ancestor, but also to every man, woman and child who seeks deliverance from evil. He will prove to all that one can be human, and yet be free of sin. He will demonstrate the power that emanates from vessels that are spiritually cleansed and powered by God. If you understand these connections and they cause you to grow in your love, honor and respect for each other, you will have aced the test.
