How would your understanding and the living out of 2 Timothy 3 (NASB) and these other verses look like?:
For men will be lovers of self, lovers of money, boastful, arrogant, revilers, disobedient to parents, ungrateful, unholy, unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good, treacherous, reckless, conceited, lovers of pleasure rather than lovers of God, holding to a form of godliness, although they have denied its power; Avoid such men as these.
1 Corinthians 5:9-10 I wrote you in my letter not to associate with immoral people; I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters, for then you would have to go out of the world.
2 John 9-11
9 Whoever transgresses and does not abide in the doctrine of Christ does not have God. He who abides in the doctrine of Christ has both the Father and the Son. 10 If anyone comes to you and does not bring this doctrine, do not receive him into your house nor greet him; 11 for he who greets him shares in his evil deeds.
Luke 6:23-35 But love your enemies, and do good, and lend, expecting nothing in return; and your reward will be great, and you will be sons of the Most High; for He Himself is kind to ungrateful and evil men.
Matthew 9:10-13
While Jesus was having dinner at Matthew’s house, many tax collectors and sinners came and ate with him and his disciples. When the Pharisees saw this, they asked his disciples, “Why does your teacher eat with tax collectors and sinners?” On hearing this, Jesus said, “It is not the healthy who need a doctor, but the sick. But go and learn what this means: ‘I desire mercy, not sacrifice.’ For I have not come to call the righteous, but sinners.”
Pro. 22:24
Make no friendship with an angry man, And with a furious man do not go,
