See how good and how pleasant it is for brothers to live together in unity!
It is like the precious oil on the head, that ran down on the beard, even Aaron's beard; that came down on the edge of his robes;
like the dew of Hermon, that comes down on the hills of Zion: for there the LORD gives the blessing, even life forevermore. A Song of Ascents.
Let us love one another, for love comes from God and every one who loves is a child of God and knows God. He who loves not man does not know God, for God is love. God showed his love for us, for he sent his only Son into the world that through him we might have life. Love the stranger.
In Mark 12:30 Jesus said;
And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this [is] the first commandment.
And the second Mark 12:31 [is] like, [namely] this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
