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.
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.
