This quote from one of my history books perfectly describes my view on what much of American Evangelism has become:
"Luther made justification by faith central; this was a healthy corrective to the erroneous Roman doctrines of the day, but it conceded to humanism, in that some who followed after Luther made the salvation of souls rather than the glory of God central to the faith."
The issue is clear, God redeems His people not for their sake, but for His. He wants His glory to be magnified. Humans were made to do that, but they will not magnify Him unless they are redeemed.
So God redeems them and makes them more like His Son Jesus Christ, the one who magnified God's glory perfectly.
