Good morning!
Greetings in the name of Father, Son, and Holy Spirit.
So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets. (Matthew 7:12)
One credit card TV commercial says “We treat you like you’d treat you.” Then it shows a short story about one card holder, who calls the credit card company. The call was answered by one of the credit card company agents, who is really kind and understanding, and provides the exact service that the caller needs. After all, the credit card company agent is self or a twin. Thus, the agent knows exactly what the caller needs, and provides precisely what the caller needs What a service! No other credit card company cannot match this kind of services. This is the message that the credit company tries to convey. Of course, this is a just TV commercial. Nobody expects his/her call is answered by himself/herself, when he/she calls a credit company for service. However, this TV commercial touches on the very heart of all of us. We want to be treated by others in the way that we really want. This is the selfishness of our nature. We all want first others to do something that we want before we are doing what they want.
Jesus Christ knew exactly the selfishness of human hearts, and Jesus told to the people around Him, “So in everything, do to others what you would have them do to you.” Rather than expecting to receive from others, do to others first what we would have them do to us. Then what does really mean?
All we have a natural tendency of thinking that we are more important or better in every aspect than others as shown in the left figure. It is very hard to get out of this mind set, and in some sense, this is not totally our fault. When we look around, every living creature is doing this. Each living creatures first treats itself until its own needs is satisfied before other creatures around it. Therefore, our “me-centric” mind set is our natural state, and the world is essentially operated by this principle. Jesus’s teaching was opposite — first get out of this “me-centric” mind set, and then consider others more important or better than us: “Don’t be selfish; don’t try to impress others. Be humble, thinking of others as better than yourselves. Don’t look out only for your own interests, but take an interest in others, too. (Philippians 2:3-4)
If this verse is pictorially drawn as a scale, it would look like the figure on the left. Then what would be really look like if we treat others better and important than us in our lives?
Apostle Paul gave one great example. He said, “So if what I eat causes another believer to sin, I will never eat meat again as long as I live—for I don’t want to cause another believer to stumble.” (1 Corinthian 8:13) At that time, the market sold meat from multiple sources. Some meat products were actually offered to idols before being brought out to market to be sold. Some were accustomed to thinking of idols as being real, so when they ate food that had been offered to idols, they thought of it as the worship of real gods, and their weak consciences were violated. In fact, it is not a problem of the person who eats the meat purchased from the market, which happened to be offered to idols, but those who had weak consciences. In other words, one’s perfectly good deed can effect negatively by making them stumble.
Apostle Paul explained this situation, “It’s true that we can’t win God’s approval by what we eat. We don’t lose anything if we don’t eat it, and we don’t gain anything if we do. But you must be careful so that your freedom does not cause others with a weaker conscience to stumble.” (1 Corinthian 8:8-9)
Let’s examine what Apostle Paul said. First, he pointed back to God and questioned: whether did his action pleased God or not. He concluded that it would not win God’s approval if he made stumble a weaker believer. Then he analyzed about his own freedom. He could eat meat offered to idols because idols are nothing. Even so, if he ate such meat, what would be his gain? If he did not eat, what would be his lose? In either case, the consequence was nothing if compared with making a weaker believer stumble by his own freedom. Then he concluded “So if what I eat causes another believer to sin, I will never eat meat again as long as I live—for I don’t want to cause another believer to stumble.” (1 Corinthian 8:13) Refraining from one’s favorite for others is really a tall order. It is not possible unless we truly care about others, especially those who are weaker than us, while considering them better and more important than us. 
Jesus said “Do to others as you would like them to do to you, ” then He continued in the book of Luke, “If you love only those who love you, why should you get credit for that? Even sinners love those who love them! Love your enemies! Do good to them. (Luke 6:32 and 36a) Jesus included enemies in the category of others, of whom He told to think better and important than us. This was not a just teaching of Jesus, but Jesus actually lived out his teaching. Jesus took the cross for those who were against Him, who shouted for Him to be crucified. He also loved those who nailed Him on cross, while praying for forgiveness of their sins. Then He died on the cross for the sins of all of us. Yes, He has no sin at all, but He died on the cross of us, who are sinful and stubbornly consider ourselves better and more important than others in many occasions.
You must have the same attitude that Christ Jesus had.
Though He was God,
He did not think of equality with God
as something to cling to.
Instead, He gave up his divine privileges;
He took the humble position of a slave
and was born as a human being.
When He appeared in human form,
He humbled Himself in obedience to God
and died a criminal’s death on a cross. (Philippians 2:5-8)
