It is easier to love those with whom we feel a common bond and share a special relationship. In fact, the Lord suggests as much in the scripture. When the Lord encouraged His people to love strangers, He did so by reminding them that they too had been strangers in the land of Egypt. By recalling their past associations, the Israelites would know how to better deal with those who were strangers to them. It would be good for them to recall some of the trials they faced when they were strangers in a strange land. With this in mind, they would know how to care for and minister to the strangers. Though Christians are not under the law and most are not Israelites, much can be learned from these truths. It becomes easier to love those to whom we can closely relate.
This verse, apart from John 3:16, may be the most recognized and certainly the most quoted verse by those who have little concern for God or the things of God. Matthew 7:1 also happens to be one of the most misinterpreted and misapplied verses in all of scripture. This verse is abused by non-Christians as well as those living a carnal lifestyle. Non-Christians do not want to be held to any biblical standard while carnal Christians attempt to use the verse to avoid having judgment passed upon them and their questionable actions. The spiritual Christian knows that the context of the verse simply discourages judging hypocritically. God never intended for His children to not judge. This passage, along with many others, simply points out the inexcusability of passing judgment upon matters where those judging are likewise guilty of the same actions. The point is not to avoid judgment altogether but to avoid hypocrisy while judging. This truth was taught during the Lord's ministry but also reiterated by the apostle Paul in Romans 2:1.
