James 4:8-12 Draw nigh to God, and he will draw nigh to you. Cleanse your hands, you sinners; and purify your hearts, you double minded. Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and your joy to heaviness. Humble yourselves in the sight of the Lord, and he shall lift you up. Speak not evil one of another, brethren. He that speak evil of his brother, and judge his brother, speak evil of the law, and judge the law: but if you judge the law, you are not a doer of the law, but a judge. There is one lawgiver, who is able to save and to destroy: who are you that judge another?
Cleansing the hands was a symbol of innocence and purity (Mat. 27:24), but here it means to separate yourself from the world and consecrate your life to God, renouncing all sin.
For those who do not dwell in the secret place of the most High, that does not abide under the shadow of the Almighty (Psa. 91:1), in reconciling with Him, you have to draw near to God again so that He can come near to you. But certain conditions are commanded to restore to your previous state. You must have no double-mindedness which refers to doubting God (Jas. 1:6-8) and you must be afflicted – mourn and weep – which shows of a true repentance that will always bring the mercy of God if done in time–that is now (1Jn. 1:7; Heb. 9:27).
Ten types of sin and pleasure are mentioned in James 4:1-9: Wars and fighting; lusts of sin (Eph. 2:1-3); murders and killings; desires – covetousness; adulteries and other sexual sins; friendships with worldly men; envies and jealousies; pride and haughtiness; laughter prompted by sin; joy founded on sin. True followers of Christ would not be guilty of those as stated repeatedly in 1 John 3.
To speak against; backbite; rail at; slander (1Pet. 2:12; 3:16)refers to slandering among the different factions of Jews and the Jews against their brethren who had accepted Christ and God is the one lawgiver and judge who is able to save or destroy. Man has no right to usurp this authority when we judge those who choose to stay in sin.
