Could Paul have been referring to ongoing tests and temptation of his flesh as his "thorn in the flesh" rather than other physical infirmities? [1 Corinthians 12:7-10, Galatians 4:13-18, Numbers 33:55, Matthew 26:41].
How detrimental is teaching the Word of Faith doctrine (Health & Wealth, Prosperity Doctrine, etc.)? And could we disprove it simply on other terms, even without scripture? [Galatians 4:13-14, 2 Corinthians 12:7-10, 2 Corinthians 8, 2 Timothy 4:20, Luke 14:33, Matthew 8:20].
Was Paul's "thorn in the flesh" actually God's allowance of demonic spirits to be sent to the Corinthian church? [2 Corinthians 12:7-9, Galatians 4:13-15, John 9].
