For He has rescued us from the dominion of darkness and brought us into the Kingdom of the Son He loves.
God calls the church to go to the world
I wrote you in my letter not to associate with immoral people; I did not at all mean with the immoral people of the world, or with the covetous or swindlers, or with idolaters, for then you would have to go out of the world.
1 Corinthians 5:9-10
God calls the church to purity
You shall follow the Lord your God and fear Him; and you shall keep His commandments, listen to His voice, serve Him, and cling to Him.
Woe to the world because of its stumbling blocks! For it is inevitable that stumbling blocks come; but woe to that man through whom the stumbling block comes! And if your hand or your foot causes you to stumble, cut it off and throw it from you; it is better for you to enter life crippled or lame, than having two hands or two feet, to be cast into the eternal fire. And if your eye causes you to stumble, pluck it out, and throw it from you. It is better for you to enter life with one eye, than having two eyes, to be cast into the fiery hell. See that you do not despise one of these little ones, for I say to you, that their angels in heaven continually behold the face of My Father who is in heaven. For the Son of Man has come to save that which was lost.
When we read the hard words of Scripture, they are always true — and they are always truly good for us. There is always an application. We always need to repent and believe. We always need to deny ourselves. We always need to obey God.
God calls the church to appropriate judgment
But actually, I wrote to you not to associate with any so-called brother if he should be an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler–not even to eat with such a one. For what have I to do with judging outsiders? Do you not judge those who are within the church? But those who are outside, God judges. Remove the wicked man from among yourselves.
1 Corinthians 5:11-13
If your brother, your mother’s son, or your son or daughter, or the wife you cherish, or your friend who is as your own soul, entice you secretly, saying, “Let us go and serve other gods (whom neither you nor your fathers have known, of the gods of the peoples who are around you, near you or far from you, from one end of the earth to the other end), you shall not yield to him or listen to him; and your eye shall not pity him, nor shall you spare or conceal him.
Who is wise and understanding among you? Let him show it by his good life, by deeds done in the humility that comes from wisdom. But if you harbor bitter envy and selfish ambition in your hearts, do not boast about it or deny the truth. Such “wisdom” does not come down from heaven but is earthly, unspiritual, of the devil. For where you have envy and selfish ambition, there you find disorder and every evil practice. But wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere. Peacemakers who sow peace raise a harvest of righteousness.
