“Rather, I would say that being incorporated into Christ is exactly what is meant by a saving Faith.”

You cannot be saved without also having been incorported into the Body of Christ.
The Holy Spirit does this.
You cannot be incorporated into the Body of Christ without first entrusting yourself to Christ’s sacrifice alone to pay for your sins and to receive eternal life.

[Mrs. Don-o]

So it's faith, incorporation into Christ, and vice versa.

Amen, AMPU!
