Draw near to God, and He will draw near to you. Cleanse your hands, sinners, and purify your hearts, double-minded people!
Be miserable and mourn and weep. Your laughter must change to mourning and your joy to sorrow.
Humble yourselves before the Lord, and He will exalt you.
Don't criticize one another, brothers. He who criticizes a brother or judges his brother criticizes the law and judges the law. But if you judge the law, you are not a doer of the law but a judge.
There is one lawgiver and judge who is able to save and to destroy. But who are you to judge your neighbor?

References for James 4:13
You don't even know what tomorrow will bring-what your life will be! For you are a bit of smoke that appears for a little while, then vanishes.
Instead, you should say, "If the Lord wills, we will live and do this or that."
But as it is, you boast in your arrogance. All such boasting is evil.
So, for the person who knows to do good and doesn't do it, it is a sin.
