so much for plans

Come now, you who say, “Today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit.” Yet you do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away. Instead, you ought to say, “If the Lord wills, we will live and also do this or that.” But as it is, you boast in your arrogance; all such boasting is evil. Therefore, to one who knows the right thing to do and does not do it, to him it is sin. — Jas 4:13-17 NASB95

Matthew Henry: 

All our actions and designs are under the control of Heaven. Our heads may be filled with cares and contrivances. This and the other thing we may propose to do for ourselves, or our families, or our friends; but Providence sometimes breaks all our measures, and throws our schemes into confusion. Therefore both our counsels for action and our conduct in action should be entirely referred to God; all we design and all we do should be with a submissive dependence on God.

Joel 2:14 King James Version

“Who knoweth if he will return and repent, and leave a blessing behind him; even a meat offering and a drink offering unto the LORD your God?”

Jesus said to them, “If you were blind, you would have no sin; but since you say, ‘We see,’ your sin remains. — Jhn 9:41 NASB95

Spurgeon:

Submit yourselves unto God"-it is what angels do, what kings and prophets have done, what the best of men delight in-there is therefore no dishonor nor sorrow in so doing. All nature is submissive to his laws; suns and stars yield to his behests, we shall but be in harmony with the universe in willingly bowing to his sway. "Submit yourselves unto God"-you must do it whether you are willing to do so or not. Who can stand out against the Almighty?
