Ross introduces a new series on Paul's first letter to the Corinthian church. He observes that the Church described in Eph 5:27 that is 'without spot or wrinkle or any such thing, that she might be holy and without blemish' is not what we see in the local church with all of our fallenness and difficulties and yet this is what God see's of us in Christ.
God see's the church more according to the hymn
The church's one foundation is Jesus Christ her Lord;
she is his new creation by water and the Word.
From heaven he came and sought her to be his holy bride;
with his own blood he bought her,
and for her life he died.
But our experience is more like verse 3 of the same hymn
Though with a scornful wonder we see her sore oppressed,
by schisms rent asunder, by heresies distressed,
yet saints their watch are keeping;
their cry goes up, "How long?"
And soon the night of weeping
shall be the morn of song.
The letter to the Corinthians is and essential message to us to put away quarrelling, divisions, disputes over custom, sexual impurity, idol worship, and pursue love and the good name of Jesus in all things.
Ross also shares a clip from The Bible Project and their excellent summary of 1 Corinthians
