If I or anyone, cannot by God’s grace, live God’s ways around you; if we cannot talk about God, His word, truths around you, with you; if us choosing to live by God’s grace causes you to get angry, curse, call us names, accuse us of not being Christian, accuse us of not having the love, character of God, bring up our sins that God has forgiven and cleansed, delivered us from (Only Satan ACCUSES); and say we are of the spirit of the devil (this is sin against the Holy Spirit to call God’s Spirit in someone the spirit of the devil); and talk about us, lie on us, and your lies to others cause them to take up reproach against us; God teaches us that we are not to choose to be among, with you. We are not to choose to fellowship with you, sit with you, dine with you- we are to choose to turn away from you. We are to pray for you, help you when God permits it for the love of God is in us… O without God we are and can do NOTHING! But O with God we can do as He did. We can do all things through Him; We are somebody because of Him in us- I give God all the glory, all honor, all praise.
God tells us, all who belong to Him this:
2 Corinthians 6:14-18 KJV
 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?  And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?  And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.  Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,  And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
Yes Jesus ate with sinners, and so do we… Yet if they received Him not, did not want to hear truth in God, about God; Jesus left, removed Himself from their presence. So are we to turn away from they who do not receive us, God’s truth- His word they do not want to hear…
God tells us this:
Mark 6:11 And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city.
Psalm 1:1-2 KJV
 Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.  But his delight is in the law of the LORD; and in his law doth he meditate day and night.
Psalm 1:4-6 KJV
 The ungodly are not so: but are like the chaff which the wind driveth away.  Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous.  For the LORD knoweth the way of the righteous: but the way of the ungodly shall perish.
1 John 1:5-7 KJV
 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.  If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:  But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
Go back through God’s word, He does not contradict Himself at all. Period.
