Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity. But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour. If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master’s use, and prepared unto every good work. Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart. 《2 Timothy 2:19-22》
Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: “I will dwell in them And walk among them. I will be their God, And they shall be My people.” Therefore “Come out from among them And be separate, says the Lord. Do not touch what is unclean, And I will receive you.” “I will be a Father to you, And you shall be My sons and daughters, Says the Lord Almighty.” (2 Corinthians 6:14-18).
When you’re set apart , you have to be careful who you walk with or entertain,because , God said , “Blessed is the man Who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful; But his delight is in the law of the Lord , And in His law he meditates day and night. He shall be like a tree Planted by the rivers of water, That brings forth its fruit in its season, Whose leaf also shall not wither; And whatever he does shall prosper. The ungodly are not so, But are like the chaff which the wind drives away. Therefore the ungodly shall not stand in the judgment, Nor sinners in the congregation of the righteous. For the Lord knows the way of the righteous, But the way of the ungodly shall perish”. (Psalms 1:1-6).
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation. Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.[2 Corinthians 5:17-21]
