I have to do a colometry here, because James is so Greeked--more than that, it's fundamentally not Greek--it's written in an unknown language and then translated into Greek and then translated into English. So the Book of James, as with many books, has been translated at least twice and maybe ten times by the time it gets to us, so it is often hard to read simply on that regard. Compare the book of Isaiah, where all the scholars tell us Isaiah was very straightforward when it was written, and that the hypotaxis of the language, more than the symbology, is what's stopping most people from really enjoying it. Anyway, James 1 is one of the best chapters in the New Testament, yet it takes.
My brethren, count it all joy when ye fall into divers temptations; Knowing this, that the trying of your faith worketh patience. But let patience have her perfect work, that ye may be perfect and entire, wanting nothing.
Count yourself lucky that you are tempted, because resisting temptation is the only way to grow, and that growth is required for salvation. It says here action based on faith is required for salvation, which action here is enduring through temptation--not ignoring it, not saying "believers cannot be tempted", not giving in every once in a while because it's still within the statistical norm.
(...)If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord (because) A double minded man is unstable in all his ways (and therefore would hurt himself if given spiritual matches.)
As an aside, the greekishness of the text, written by the brother of Jesus, may imply that Jesus spoke a lot, if not primarily, Greek. That is not unusual--Greek was actually more spoken than Latin even in downtown Rome. It is important to recognize that we don't
know what language Jesus spoke, and any arguments for any language hold no more weight than this argument here.
