"Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Christ Jesus is in you—unless, of course, you fail the test? And I trust that you will discover that we have not failed the test." -- 2 Corinthians 13:5-6
The following explanation is found on the SAT web site: "The SAT and SAT Subject Tests are a suite of tools designed to assess your academic readiness for college... measuring the skills required for success in the 21st century." Simply put, this is a test to discover your knowledge and skill for further study and success. For many, their future depends on the results.
Paul never took anything for granted. When he wrote to these believers in Corinth, he challenged them to test themselves. He may have offended some, but such a test is far more important than any SAT exam. This is the final test to discover your position with Christ. Is Jesus your Lord and Savior or not? For everyone, their future depends on the results.
When did you take that step of faith my friend? Was it a sincere confession of sin, repentance toward God and faith in Jesus Christ as your only means of salvation? Has your life been transformed by the Spirit of God living within your heart? Don't blow it off; test yourself now, because your future depends on the results.
