How do we know God's purpose for unity among Christians?

Romans 15:6 states that God's purpose in granting patience and like-mindedness among believers is that 'ye may with one mind and one mouth glorify God.' This reflects the intent of God to unify His people under the truth of the Gospel. God's plan is to gather together in one all things in Christ, demonstrating that unity glorifies Him. True oneness among believers is not merely a social construct; it is a testament to Christ's work in reconciling us both to God and to each other, resulting in a harmonious body that lives for His glory.
