You are a mist that appears for a little while and then vanishes.
James is talking about the brevity of life.
Visit with those who have lived to be a hundred years old. They will not speak of long life. Instead, they seem surprised at how fast the time flew by.
We aren’t promised a tomorrow. Physical bodies all come with a lifetime warranty, but the problem is some lifetimes are not very long!
Life is fragile, uncertain. Anything may happen.
Yesterday is gone, tomorrow may never come. Today is all we can be sure of in this life.
That’s why the Lord’s will is so important!
Because at the end of life, we pass through the door of death to behold the face of God! Then we will fully realize the importance of our relationship with Him.
Gone will be the false ideas that we are in charge of our own destiny. We make our plans and will have what we will have!
There is a limit to the power of man to determine his own fate. That’s why James counsels us to begin to include Jesus in all our daily plans now - If it is the Lord's will, we will live and do this or that.
Someday soon for all of us it will be very clear just how dependent we are upon the Lord for everything. But whether we understand this fact or not, it remains the everyday truth nonetheless.
And that’s why James reminds students of Jesus to be busy doing the good they can do – while they can!
Anyone, then, who knows the good he ought to do and doesn't do it, sins.
