Nobody loves my Evangelical brothers and sisters as much as I do, but "profitable" is not a synonym for "complete" or "all-encompassing" in ANY language.
I couldn’t agree more.
So maybe YOU can or will answer this question.
What else is divinely inspired writing by the Holy Spirit that DIDN'T make it into the Bible that qualifies as Scripture, and is active and living and sharper than any double edged sword, that is able to make one wise unto salvation, that is truth, is profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work, that is settled in heaven forever, is sent out by God and does not return to Him empty but accomplished the work for which He sent it out, so that we can believe that Jesus is the Christ, the Son of God, and that by believing we may have life in his name, and which is written so that we can know that we have eternal life?
