Deep Spirited Friends

Philippians 2:2 in the Message reads: “If you’ve gotten anything at all out of following Christ, if His love has made any difference in your life, if being in a community of the Spirit means anything to you, if you have a heart, if you care—then do me a favor:  Agree with each other, love each other, be deep spirited friends.”   What are the characteristics of deep spirited friends and why are they important in the life of a woman?
