Unity only comes from and through the Lord Jesus Christ, but once it comes, the saints of God must endeavour to keep that unity. One of the reasons why people find unity so elusive is because it requires sacrifice from all those who would enjoy its benefits. Only saints who exercise “lowliness and meekness, with longsuffering” will experience unity. No two believers who are using the minds that God gave them will believe every minute detail alike, yet they can enjoy sweet unity and fellowship in the Lord. Obviously, there are times and reasons for believers to divide, but there are also times for believers to forbear “one another in love” and endeavour to keep the unity. This unity works by love and can only be bonded through peace.
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.
