James is stressing in this passage from chapter 5 of his book for us to be patient until the Lord's coming. Patience is definitely an important attribute for us to have as Christians - though many times may not be the easiest one to have. James also writes in the 1st chapter of his book the following words:
"Count it all joy when you fall into various trials - knowing that the testing of your faith produces patience. But let patience have it's perfect work, that you may be perfect and complete, lacking nothing."
How hard is it to find joy when we fall into a trial?? What's the easy thing to do? - Complain? Give up? Get Angry? Probably a little bit of all those things. Whether they be spiritual trials or trials with family or friends or trials at work - we need to try to see the positive side of them. In doing this, our faith in God is going to grow and we will develop more patience. Take the words of James and apply them into your own life - "Be Patient Until the Lord Comes."
