Is making a lot of money legit?

Is it legitimate to pursue making a lot of money as an end in itself? No.

However, note the above says the love of money is the problem, not money itself.

If we diligently pursue doing things with excellence for the glory of God it is absolutely not only legitimate to be as productive and fruitful as possible but what we are called to do. 

From the beginning and throughout the New Testament, God's mandate to humanity was to be fruitful and multiply i.e. bear much fruit. This honors God.

This may result in financial success (and sometimes does, particularly if God gave you the temperament and skills to be an effective business person). But it's not automatically a guarantee. 

Since making money is not the focus (though it can clearly be a legitimate measuring stick of success under the right conditions), but the pursuit of excellence for Christ's sake is, do everything - including "business" - for God's honor (glory) regardless of whether we see a significant financial reward or not. 

We should always strive for excellence and never back off being as fruitful as possible. That is not necessarily just biologically but spiritually and materially. Doing things with excellence has more to do with effort and intent than outcome. Backing off from doing all things for God's glory is not optional. Honoring God in all we say and do is the calling of every believer.
 

What about our skills?

What if our skills and abilities, energy, stamina, strength, and mental sharpness have considerably dropped off with age or for some other reason such as overall health or injury? Is this a legitimate reason to slow down? 

Because money is not the final measuring stick of a legitimate endeavor but intent to honor God is, we are still to pursue things with excellence regardless of our skills i.e. being excellent for Christ's sake always remains the ¹same even though our abilities change over time (some for better - like increased wisdom through increased life experience - and some for worse, like declining physical and mental stamina). 

Doing everything with excellence for the glory of God should ²always be our goal and modus operandi regardless of the resources or skills we may or may not have; whether those resources change, decline, or increase.

What about excellence vs doing just enough to "get by?"

Excellence in the marketplace in contrast to the lack of excellence provides a greater opportunity to put God on display; to demonstrate that living for God is a more excellent and productive way than not living for him. 

This is exactly why Joseph excelled in every circumstance he found himself in and was entrusted to oversee things wherever he went. He was eventually promoted to second in command in Egypt, probably the greatest nation in the world at that time. This led to great prosperity and the saving of many lives, including his own family. 

Truly knowing and living for God makes us more productive, resourceful, and excellent, resulting in greater honor to God and service to fellow bearers of God's image.

Excellence in attitude.

We are not only to be excellent in our effort but excellent in attitude e.g. humble, diligent, caring, etc. which usually, though not automatically, leads to an excellent outcome. In fact the right attitude leads to the right outcome. Therefore, knowing God is more excellent in the work environment (or any area of endeavor) than not knowing Him.  It is the superior way of living life. 

But we must distinguish between truly knowing God versus knowing about God. They are not the same. 

Whether you eat or drink or whatever you do, do all to the glory of God.

Ecc 9:10  Whatever your hand finds to do, do it with your might, for there is no work or thought or knowledge or wisdom in Sheol, to which you are going.

Do – G4160

From G5594; breath, that is, (by implication) spirit, abstractly or concretely (the animal sentient principle only; thus distinguished on the one hand from G4151, which is the rational and immortal soul; and on the other from G2222, which is mere vitality, even of plants: these terms thus exactly correspond respectively to the Hebrew [H5315], [H7307] and [H2416]: - heart (+ -ily), life, mind, soul, + us, + you.

As a believer in business for over 40 years, I have wrestled with what is legitimate and what is questionable in "doing business." 

The following links are some conclusions I have come to so far, based on scripture first and my own experience, failures, struggles, and successes. 

For those who have wrestled with these same things, I trust you will find the below helpful.
