Question: This cliche is usually *quoted* in the context of "the ends don't justify the means", but in *practice* most folks seem to live as if the ends did justify the means even if the means involved sin. However sometimes people cannot see clearly what is sin and what isn't. An example might be with-holding information from a loved one so as not to upset them.

While on clear situation of sin they might come down one way, given a predicament where the right choice isn't clear to a person, they often turn this cliche the other way around and tell themselves that the ends *do* justify the means.

Is there any Biblical content that speaks to this cliche one way or another. Is there a good "retort cliche" that one could use as a reminder of the proper way to make a moral or ethical decision in light of Christian teachings?

Answer: 
The idea that "the ends justify the means" admits that there is something inherently wrong with "the means". Indeed, it admits that "the means" are actually **unjustified** by themselves. The claim, then, is that although "the means" are unjustifiable in themselves, that a particular outcome that is achieved by them results in the justification of the unjustified. 

Christianity certainly **does not** have any basis for this idea, and it doesn't need any. I know of a particular religion that believes it's alright for its followers to lie in a conversation with someone of another religion if lying helps them win the argument. Christianity, however, does not need to do this, because Christianity believes that truth is on its side. That's a key point, because Truth invites questioning, whereas lies and falsehoods do not.

God calls us to do what is righteous and then trust Him for the results.
No, it is not compatible with Christianity. Consider this verse:

> 
> Heb 8:5 Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount. 
> 
> 
> 

If we do not do things according to the word, it isn't right no matter how much perceived good may come. We must do everything "according to the pattern" God has revealed in His word. Dr. Bob Jones Sr. used to say, "It's never right to do wrong." That's a cliche we as Christian ought to have. 

Consider those "Christians" out there who use the "ends justify the means" logic in evangelism. Instead of using the law to show them their need of Christ, they simply ask through the screen door, "Do you want to go to Heaven? Ok, say this prayer... you're in." For many, many folks, a decision can justify any method, no matter how ungodly it might be.

Results should never be a basis for judgement when it comes to our faith.
