Agree with one another in love

“Therefore if there is any encouragement in Christ, if there is any consolation of love, if there is any fellowship of the Spirit, if any affection and compassion, make my joy complete by being of the same mind, maintaining the same love, united in spirit, intent on one purpose. Do nothing from selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves…” (Phil. 2:1-3)

Agree with one another in the same mind and same judgement

“I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of you agree, and that there be no divisions among you, but that you be united in the same mind and the same judgment.” (1 Cor. 1:10 ESV)

The power of agreement

“Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven.” (Matt. 18:19 ESV)

Therefore…

“Now may the God who gives perseverance and encouragement grant you to be of the same mind with one another according to Christ Jesus…” (Rom. 15:5)
