You are no longer strangers and sojourners,
but you are fellow citizens with the holy ones
and members of the household of God,
built upon the foundation of the Apostles and prophets,
with Christ Jesus himself as the capstone.
(Eph 2:19-20)
I love the old hymn, How Firm A Foundation. I grew up with this hymn; it’s a part of my soul. Of course, the hymn was talking about the Word of the Lord being the foundation of our lives. But I think the hymn also applies to the foundation of the Apostles and prophets through whom we have received that Word. As the Letter to the Ephesians suggests, It is Christ Jesus himself who holds the whole structure together.
