“In everything do to others as you would have them do to you; for this is law and the prophets.
“Enter through the narrow gate; for the gate is wide and the road are easy that leads to destruction, and there are many who take it. For the gate is narrow and the road is hard that leads to life, and there are few who find it.
“Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will know them by their fruits. Are grapes gathered from thorns, or figs from thistles? In the same way, every good tree bears good fruit, but the bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will know them by their fruits.”
In verse 12 Jesus sums up basically the entire Old Testament in to one sentence. Do unto others as you would want them to do to you. As we teach children, treat others the way you want to be treated. Notice Jesus doesn’t say the way they actually treat you, but the way you want them to. Also notice it doesn’t mean they are obligated to treat you the same way. In fact, they probably won’t. But when you treat them well you are doing the right thing.
It has always puzzled me that Jesus doesn’t say what the narrow gate IS. But in context here, I think the Golden Rule is the narrow gate. It (the Golden Rule) is difficult to do, and few succeed. But it leads to eternal life. Anything else is sinful. That’s why that gate is wide. There are a lot more ways to treat someone poorly than there are to treat someone well!
Jesus’s warning against false prophets is especially relevant today. There are so many church leaders now that some are bound to get things wrong. And, unfortunately, they all have access to the internet and TV, so they can get their message out to millions. You have to be careful and really ask yourself if they have good fruits. The Westboro Baptist Church, for example, has so many bad fruits that you know they must have a bad leader. You can’t trust anything he says because his words are not from God. I wish more of the members could see that.
