And if he shall neglect to hear them, tell it to the church: but if he neglect to hear the church, let him be to you as an heathen man and a publican. – Matthew 18:17
God has principles in treating man, so He requires us to treat others in a principled way. If a person sins, as long as he can repent, God will not abandon him. If he, after being helped many times, never accepts or repents, we will keep far away from such person. Just as God says: “What does God’s word require as the principle for treating others? Love what God loves, hate what God hates. That is, the people loved by God who truly pursue the truth and who carry out God’s will, are the people you should love. Those who don’t carry out God’s will, hate God, disobey God, and are despised by God, are people we should despise and reject. That’s what God’s word requires.” We should treat others according to what God’s word requires. God loves those who pursue the truth, practice His words and accept others’ suggestions; He hates those who don’t accept the truth, practice the truth despite clear awareness of it, or listen to others’ suggestions.
