Why "winning" as the goal ought to be anathema to Christians

To 'win', at all cost, and by all means, whether in business, politics, or personal relationships, is an idea embedded in the human heart.  Unfortunately, the disregard for morality, and the value of other people, in the pursuit of 'victory', is a symptom of the darkened heart of mankind apart from God.  As such, the people of God, those who have been redeemed by the blood of the Lamb, and are therefore no longer under the power of what the Apostle Paul terms, the "flesh" (our sinful nature), must forcefully and consistently reject the false claim that "the end justifies the means".

The modern era is not the first time that attempts have been made to remove morality as a check on human behavior, the Italian Renaissance political philosopher Niccolo Machiavelli advocated the divorce of morality from politics in his seminal work, The Prince.  In it he wrote, "He who neglects what is done for what ought to be done, sooner effects his ruin than his preservation."  Thus, immorality is to be excused when it is deemed necessary, hence the association with the immoral claim that "the end justifies the means."  Machiavelli, while influential, was certainly not the first to treat morality as a hindrance to be disregarded when necessary.  The first king of Israel, Saul, convinced himself that he needed to offer a sacrifice to God prior to an upcoming battle, despite knowing that he was not to usurp the role of the prophet Samuel, because necessity demanded it.  Saul's disregard for the expressed will of God was instrumental in his downfall and the choice of David to replace him.  By contrast, in Scripture there are examples of the rejection of this abdication of morality: Joseph remained true to the moral code of the God of Abraham despite the opportunities he had to abandon it when faced with the advances of Potiphar's wife.  Even as a wrongly enslaved man, Joseph refused to set aside his devotion to doing what was right.  In addition, the Apostle Paul and Silas refused to run from jail in Philippi, despite being unlawfully imprisoned, when an earthquake damaged the facility.

Throughout the Scriptures, those who abandon morality when convenient come to bad ends and those who hold true to the Law of God (whether specifically or in principle) are commended.  That is not to say that those who choose to do what is right are always vindicated in this life, nor are they promised such by God, neither do all those who choose to set aside right/wrong receive punishment for their immorality in this life.  Therein lies the rub.  When righteousness is not immediately rewarded, and wickedness is not immediately punished, the selfish and rebellious heart of man begins to seek ways to avoid the absolute demand of God that we live holy and righteous lives, it seeks loopholes, shortcuts, compromises, and makes Faustian bargains.  Such is the darkness of the heart of man in rebellion against God.  For the people of God, however, this cannot be tolerated or excused.  When we go along with immoral means with the hopes of achieving an end we deem to be worthy, we sully the name of Christ and grieve the Holy Spirit.  When we choose power, wealth, fame, or any other moniker of 'success', pursued by immoral actions, we abdicate our responsibility to be salt and light in this world, endanger our witness to the Lost, and call into question the genuineness of our conversion and discipleship.  

For all those who prioritize 'winning' or 'victory' above the call of God to live always, and in all things, according to his Holy Word, a series of warnings from God are a reminder of the futility of that path.

Psalm 1

1 Blessed is the one

    who does not walk in step with the wicked

or stand in the way that sinners take

    or sit in the company of mockers,

2 but whose delight is in the law of the Lord,

    and who meditates on his law day and night.

3 That person is like a tree planted by streams of water,

    which yields its fruit in season

and whose leaf does not wither—

    whatever they do prospers.

4 Not so the wicked!

    They are like chaff

    that the wind blows away.

5 Therefore the wicked will not stand in the judgment,

    nor sinners in the assembly of the righteous.

6 For the Lord watches over the way of the righteous,

    but the way of the wicked leads to destruction.

Ephesians 5:5-7 New International Version (NIV)

5 For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God.  6 Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient. 7 Therefore do not be partners with them.

Romans 3:8 New International Version (NIV)

8 Why not say—as some slanderously claim that we say—“Let us do evil that good may result”? Their condemnation is just!

It may seem possible to play in the mud without getting dirty, it may seem possible to make bargains with or support others who act immorally without ourselves becoming tainted, but these are lies, lies from the Father of Lies, and lies of a mind not in submission to the will of God.  The choice is clear: Either we, as God's people called from darkness into light, walk in the light, win or lose, success or failure, or we don't.  

Mark 8:36-37 New International Version (NIV)

36 What good is it for someone to gain the whole world, yet forfeit their soul? 37 Or what can anyone give in exchange for their soul?
