" Evil is as Evil does! "

Matthew 24:12 

"And because iniquity shall abound, the love of many shall wax cold."

 " Evil is as Evil does! "

The only reason that an abundance of iniquity would make anyone's love for the Lord wax cold, is if he were not separated from that iniquity. 
As with Lot, a righteous man can vex his soul from day to day by hearing and seeing the unlawful deeds of the ungodly (2 Pet. 2:4-11).

Doom of False Teachers

⁴ For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; ⁵ and did not spare the ancient world, but saved Noah, one of eight people, a preacher of righteousness, bringing in the flood on the world of the ungodly; ⁶ and turning the cities of Sodom and Gomorrah into ashes, condemned them to destruction, making them an example to those who afterward would live ungodly; ⁷ and delivered righteous Lot, who was oppressed by the filthy conduct of the wicked ⁸ (for that righteous man, dwelling among them, tormented his righteous soul from day to day by seeing and hearing their lawless deeds)— ⁹ then the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment, ¹⁰ and especially those who walk according to the flesh in the lust of uncleanness and despise authority. They are presumptuous, self-willed. They are not afraid to speak evil of dignitaries, ¹¹ whereas angels, who are greater in power and might, do not bring a reviling accusation against them before the Lord.


We have to deal with the world's system and those in it, but we need to be careful and maintain proper balance. We should shun relationships with those who influence us negatively more than we influence them positively.

Marriage:
Marriage is one area where this principle is especially true. 
There is no closer union in life than the marriage relationship. 
A believer who marries an unbeliever is directly violating this scripture and is toying with disaster. 
The Lord should be the most important person in our life. 
How could we possibly become "one" with a person who doesn't love our Lord?

It is folly to think that after marriage an unbelieving spouse will accept the Lord. Although that does happen, it cannot be guaranteed. In fact, statistics are overwhelmingly against this happening. Regardless of that possibility, a believer who marries an unbeliever is directly violating God's instructions here. It is not a good start to any marriage to spurn God's Word.

Being unequally yoked with unbelievers just doesn't work. 
Believers and unbelievers are as different as righteousness and unrighteousness, light and dark, up and down, Christ and the devil. 
One has faith and the other has none. 
One is the temple of God and the other an idol. 

" Without Faith is it is possible to please God! "

Any Christian who doesn't see this conflict is deceived.
