1 Timothy 4:13-17

I was reading through 1 Timothy today and came accross these few verses and it really hit me hard since the past few days I've been worried about a alot of stuff...so here it is:

1Timothy 4:13-17
Now listen, you who say, "Today or tomorrow we will go to this city, spend a year there, carry on business and make money." What is your life? You are a mist that appears for a little while and then vanishes. In stead, you ought to say, "If it is the Lord's will, we will live and do this or that." As it is, you boast and brag. All such boasting is evil. Anyone, then, who knows the good he ought to do and doesn't do it, sins."
