Psalm 133 contains a goal, hope, and prayer for unity within just three verses. It can serve as a rallying cry for unity in God's church today, which is disunited and fractured into many small groups. True unity requires humbly submitting to God's terms rather than our own agendas. Verse 1 says it is good and pleasant when brethren dwell together in unity. Unity pleases God and benefits His people. Verses 2-3 use metaphors of oil and dew to illustrate that unity comes down to us from God via the Holy Spirit. It covers Christ's entire body. Eternal life is commanded by God to those abiding in unity within His church. We must respond to God's command for unity through practical actions. If we strive for unity, God will supply the Spirit. With effort and sacrifice on our part, unity and its blessings will spread in the church.
