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.  And he shall be like a tree planted by the rivers of water, that bringeth for his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper. (Psalms 1:1-3)

For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. (1 Corinthians 6:20)

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.  Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God. (II Corinthians 6:14-18; 7:1)

For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. (Galatians 6:13,16)

I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, with all lowliness and meekness, with longsuffering, forbearing one another in love; endeavoring to keep the unity of the Spirit in the bond of peace. (Ephesians 4:1-3)

That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; But speaking the truth in love, may grow up into him in all things, which is the head, even Christ.  (Ephesians 4:14,15)

If so be that ye have heard him, and have been taught by him, as the truth is in Jesus:  that ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts; and be renewed in the spirit of your mind; and that ye put on the new man, which after God is created in righteousness and true holiness.  Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another.  Be ye angry, and sin not: let not the sun go down upon your wrath: neither give place to the devil.  Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth.  Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.  And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.  Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: and be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you. (Ephesians 4:21-32)

Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, by a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; and having an high priest over the house of God; let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.  Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) and let us consider one another to provoke unto love and to good works: not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.  For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, but a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.  He that despised Moses' law died without mercy under two or three witnesses: of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the convenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?  For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord.  And again, The Lord shall judge his people.  It is a fearful thing to fall into the hands of the living God. (Hebrews 10:19-31)
