Behold, how good and how pleasant it is For brethren to dwell together in unity!

Behold, how good and how pleasant it is For brethren to dwell together in unity! It is like the precious oil upon the head, Running down on the beard, The beard of Aaron, Running down on the edge of his garments. It is like the dew of Hermon, Descending upon the mountains of Zion; For there the Lord commanded the blessing— Life forevermore.   Psalm 133:1-3 - NKJV

Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you at the revelation of Jesus Christ; as obedient children, not conforming yourselves to the former lusts, as in your ignorance; but as He who called you is holy, you also be holy in all your conduct, because it is written, “Be holy, for I am holy.” And if you call on the Father, who without partiality judges according to each one’s work, conduct yourselves throughout the time of your stay here in fear; He indeed was foreordained before the foundation of the world, but was manifest in these last times for you who through Him believe in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God. Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart, having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever, because “All flesh  is  as grass, And all  the glory of man as the flower of the grass. The grass withers, And its flower falls away, But the  word of the  Lord  endures forever.” Now this is the word which by the gospel was preached to you.
1 Peter 1:13-17,20-25 -NKJV
