6 Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? 7 Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed. 8 Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.
9 I wrote to you in my letter not to associate with sexually immoral people — 10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. 11 But now I am writing to you that you must not associate with anyone who claims to be a brother or sister but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people.
12 What business is it of mine to judge those outside the church? Are you not to judge those inside? 13 God will judge those outside. “Expel the wicked person from among you.” 1 Corinthians 5:6-13
There are six classifications of sinners that Paul speaks against: sexually immoral, greedy, idolatry, slander, drunk, and swindler. If a person does not want to change their ways, then Paul’s command is clear: don’t even have lunch with them, unless it’s to persuade them against their egregious sin.
These are harsh words to hear because we don’t like to think these people exist in the church. It’s a warning for Believers as well. God does not tolerate sin. He is gracious and forgiving but He shouldn’t be put to the test.
Examine your heart today. Draw close to Him throughout the day. Take the time to just stop and praise Him.
