When Paul writes to the Christians living in and around Ephesus, he refers to God's plan of salvation as a "mystery." To the Christians of today, hopefully this "mystery" sounds like a regular Sunday sermon. Salvation by grace alone through faith alone in Christ alone is what we are called to preach and teach.

What may not be so obvious to the Christians of today is we can follow the "mystery" of our salvation from before God created to our present day. God has consistently revealed His salvation in a most mysterious way – through the weakness and brokenness of those He calls to be His own.
