Guardning against spiritual sickness

2 Corinthians 6:14–18 KJV 1900

14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? 15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? 16 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. 17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you, 18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.

Psalm 101:3–4 KJV 1900

3 I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me. 4 A froward heart shall depart from me: I will not know a wicked person.

1 Peter 1:15–16 KJV 1900

15 But as he which hath called you is holy, so be ye holy in all manner of conversation; 16 Because it is written, Be ye holy; for I am holy.
