James 4:13-17 Go to now, you that say, today or tomorrow we will go into such a city, and continue there a year, and buy and sell, and get gain: Whereas you know not what shall be on the morrow. For what is your life? It is even a vapour, that appear for a little time, and then vanish away. For that you ought to say, If the Lord will, we shall live, and do this, or that. But now you rejoice in your boastings: all such rejoicing is evil. Therefore to him that know to do good, and do it not, to him it is sin.
Boastings here consist of bragging on buying and selling from city to city and what one will do here and there. One should always say, “If the Lord will, we shall live to do this, or that”. This would demonstrate a personal faith in God and His providence instead of one’s own abilities. All such boasting is of evil intent. We cannot travel, shop, work or live life from our own understanding and ideas, we have to trust in God and acknowledge Him in all our ways, then He can direct our paths (Pro. 3:5-6).
God’s will is always to make us perfect in every good work to do His will, working in you that which is well-pleasing in His sight, through the Lord Jesus Christ (Heb. 13:21).
For what is your life? It is a vapour…This is practically what was said of the rich man in James 1:10-11, so little worth to one’s life whom only focuses on the riches and ‘success’ of this world. The last verse warns that if we know what is good – to do right according to God’s standards – and we don’t, we are sinning. The Greek word for sin is hamartia which means to miss the mark.
