James 4:13-17 New Revised Standard Version (NRSV)
Boasting about Tomorrow
13 Come now, you who say, “Today or tomorrow we will go to such and such a town and spend a year there, doing business and making money.” 14 Yet you do not even know what tomorrow will bring. What is your life? For you are a mist that appears for a little while and then vanishes. 15 Instead you ought to say, “If the Lord wishes, we will live and do this or that.” 16 As it is, you boast in your arrogance; all such boasting is evil. 17 Anyone, then, who knows the right thing to do and fails to do it, commits sin.
James 5:7-11 New Revised Standard Version (NRSV)
Patience in Suffering
7 Be patient, therefore, beloved,[a] until the coming of the Lord. The farmer waits for the precious crop from the earth, being patient with it until it receives the early and the late rains. 8 You also must be patient. Strengthen your hearts, for the coming of the Lord is near.[b] 9 Beloved,[c] do not grumble against one another, so that you may not be judged. See, the Judge is standing at the doors! 10 As an example of suffering and patience, beloved,[d] take the prophets who spoke in the name of the Lord. 11 Indeed we call blessed those who showed endurance. You have heard of the endurance of Job, and you have seen the purpose of the Lord, how the Lord is compassionate and merciful.
