Your life in Christ makes you strong, and his love comforts you. You have fellowship with the Spirit, and you have kindness and compassion for one another.
References for Philippians 2:1
I urge you, then, to make me completely happy by having the same thoughts, sharing the same love, and being one in soul and mind.
Don't do anything from selfish ambition or from a cheap desire to boast, but be humble toward one another, always considering others better than yourselves.
And look out for one another's interests, not just for your own.
