And put away evil from Israel - Judges 20:13
The earnestness and promptness with which Israel dealt with and put away this evil thing were very commendable. They had gathered from all the land, even from Gilead beyond the Jordan. They were knit together in a perfect unity of feeling and action. They resolved to subordinate all things beside to the excision of this evil.
So must it be in the Church. The Lord Himself took Ananias and Sapphira out of the infant Church; and the Apostle very earnestly besought and commanded the Corinthians to put away from among them the wicked person, who had committed a sin that would not be named among the Gentiles. "Christ our Passover is sacrificed for us; therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth" (1Co 5:7-8).
At the close of this age God will send forth His angels, to sever the wicked from among the just, and to cast them into the furnace of fire.
In our own life it is impossible altogether to avoid contact with such people. Indeed, to do so, as the Apostle says truly, we must go out of the world. But we can abstain from their friendship and company. It is an altogether different thing to have dealings with a worldly man in business, and to admit him into bosom fellowship and comradeship in our leisure hours. The first is permissible, but not the second; else our companions will seduce us from our loyalty to God. Beware of taking on the color of the ground on which you lie. "I pray not that Thou shouldest take them out of the world, but that Thou shouldest keep them from the evil."
