Eph. 4:3,4 Be faithful to guard the sweet harmony of the Holy Spirit among you in the bonds of peace, being one body and one spirit, as you were all called into the same glorious hope of divine destiny. - The word guard means - watch over in order to protect, protect against damage or harm. You and I, as Christ-like-ones, are called to watch out for one another. The Bible tells us to encourage, strengthen, believe the best, and as much as it is possible within us, to keep and maintain peace with our fellow believers. Sure, there are times when we are all challenged in our love walk, but it's up to you and I to protect the sweet harmony we have with others, because we all carry the same Holy Spirit of peace within us.
