Man, There's nothing like it.
Psalm 133 says:1Behold, how good and how pleasant it is for brethren to dwell together in unity!
2It is like the precious ointment upon the head, that ran down upon the beard, even Aaron's beard: that went down to the skirts of his garments;
3As the dew of Hermon, and as the dew that descended upon the mountains of Zion: for there the LORD commanded the blessing, even life for evermore.
Oil refers to the Anointing of the Holy Ghost. When your brothers are driving you to be closer to God, you receive so much more than just walking it alone.
As dew makes the desert grass grow, so iron sharpens iron, as one man sharpens another. Without the brotherhood, who will tell you when you are wrong? Who will push you to share your Gift?
See, i want the blessing, the commanded blessing of the Lord. And that's tied to brotherhood!
