If a brother meets a brother
Walking in the Lord,
There's a joy that's like no other,
Both in one accord.
Whether short the time or longer,
Whether night or day,
Each one makes the other stronger
As they talk and pray.
Behold, how good and pleasant it is
when brothers dwell in unity!
It is like the precious oil on the head,
running down on the beard,
on the beard of Aaron,
running down on the collar of his robes!
It is like the dew of Hermon,
which falls on the mountains of Zion!
For there the LORD has commanded the blessing,
(Psalm 133 ESV)
Those who are in Christ Jesus have a unity, a family relationship, which is an amazing gift from God. They may be new acquaintances, but they are one.
