Cooperation is working together with other units in the same army or with other nations against a common enemy. When we apply it to the spiritual war, there are two much stronger terms for it: love for the brothers and unity in the body. This love is a very strong witness to the lost.

Love for the Brothers

“A new command I give you: Love one another. As I have loved you, so you must love one another. By this all men will know that you are my disciples, if you love one another” (Jn. 13:34–35).

This is a major issue in evangelism. When the unsaved man looks at the fighting between Christians or Christian churches, why would he think we were followers of Jesus? Or why would he want to be a follower of Him?

“For we were all baptized by one Spirit into one body— whether Jews or Greeks, slave or free—and we were all given the one Spirit to drink” (1 Cor. 12:13).

“As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received. Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit—just as you were called to one hope when you were called—one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all” (Eph. 4:1–6).

If you do not love the brothers, fix that beforeyou start evangelizing.
