What does the Bible say about unity among believers?

Psalm 133 highlights the beauty and blessings of unity among God's people. It declares, 'Behold, how good and how pleasant it is for brethren to dwell together in unity!' This unity is not simply a social construct; it is a God-given blessing that reflects the relationship we have in Christ. Through unity, believers experience the presence of Christ among them, as affirmed in Matthew 18:20, where Jesus promises, 'For where two or three are gathered together in my name, there am I in the midst of them.' Thus, unity is essential in the church and encourages mutual support and love among believers.
