I definitely agree about the “devil’s advocate” approach not being edifying. Some believe that “playing” this role somehow offers insight needed to grow in Christ. Thos who have been aquainted with the Devil can attest to its wickedness. I don’t believe anyone who truly knows Jesus Christ would want to be Satan’s advocate, whether or not they call it playing.
We need the Truth, the Whole Truth and nothing but the Truth. Jesus Christ is alive, and His Spirit it VERY real. All we have to do, as someone has pointed out, is to focus on Him. Life is ALL ABOUT Jesus Christ. So, Christianity is ALL ABOUT Jesus Christ, not manmade tradition, not psycology.
Though many “churches” are defunct, the Church of the Lord Jesus Christ remains, and will until He Returns to get us!
