These be the reasons why many are "called out" from the churches which was supposed to be called out from the world.
1 John 1:3 That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. 4 And these things write we unto you, that your joy may be full. 5 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. 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: 7 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. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
Ephesians 5:1Be ye therefore followers of God, as dear children; 2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour. 3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints; 4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks. 5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. 6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. 7 Be not ye therefore partakers with them. 8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: 9 (For the fruit of the Spirit is in all goodness and righteousness and truth;) 10 Proving what is acceptable unto the Lord. 11 And have no fellowship with the unfruitful works of darkness, but rather reprove them. 12 For it is a shame even to speak of those things which are done of them in secret. 13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. 14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. 15 See then that ye walk circumspectly, not as fools, but as wise, 16 Redeeming the time, because the days are evil. 17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
2 Corinthians 6:14 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.
Scripture did prophesy that in the latter days before the Bridegroom returns, even Jesus had asked the question, will He find faith in all the earth?
Luke 18:7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? 8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?
