In Unsearchable Riches, part three we discover that it had been God’s eternal purpose in uniting Jews and Gentiles into one body through the church. God knew in advance what he was going to do and the great sacrifice it would take to bring all of this together. As a result, through Christ’s sacrifice we have obtained two more treasures where we now have access to approach God’s throne with boldness.

This was in accordance with the eternal purpose which He carried out in Christ Jesus our Lord, in whom we have boldness and confident access through faith in Him. Therefore I ask you not to lose heart at my tribulations on your behalf, for they are for your glory.
Ephesians 3:11-13 NASB
