Matthew 7: 12
Therefore, however you want people to treat you, so treat them, for this is the Law and the Prophets.
God spent the entire Old Testament pointing out the way we should go. He gave us rules which were meant to guide us and keep us from harm. I think of these statements from God as very similar to when we tell a child not to touch the burner on the stove. That instruction is not meant to rob the child of any liberty but rather to protect him. This is what the Law and the Prophets did for us. Those words point out the safe and also lucrative paths.
So, with that background, we reach the question of why we should adhere to the Golden Rule. Another way we have heard the Golden Rule stated is, “Do unto others as you would have them do unto you.” In other words, treat people the way you want to be treated. Well, why? The answer is because it is in your best interest. When we truly understand that the Kingdom of God operates according to the principle of sowing and reaping then so many of the Bible’s admonitions make sense. Father God gives us specific directions because He knows what the outcome will be for us. As you have undoubtedly heard many pastors teach, forgiveness of someone is not for their sake but for your own.
God has marked out the path. He has advised us of actions specifically to do, as above and acts to intentionally avoid, such as judging others. His motivation in giving these guidelines is the same for each. He is attempting to bring us into a good place. He has demarcation lines which, if followed, will lead us to the land flowing with milk and honey. We fail to follow the correct path sometimes because it looks like a path of rules and restrictions. Nothing could be further from divine reality. In absolute truth, these pathways lead us to greater freedom, victory and success. All the ways of God are filled with His glory and goodness. His aim is to lead you in the way you should go so that you avoid pain and experience success. So, when you read the Bible and see what looks to you like a rule, refocus your eyes and see advice from the wisest of all, advice which will always lead you into abundance and joy. Such is the Golden Rule. Be kind to others. Treat them as you wish they would treat you because God wants to nurture and fertilize your good seed.
