Biblical Investing?

During link-hooping today, I spotted a post on "Free Money Finance" (don't ask me how I got there) -- Biblical Investing. Not sure whether the site is operated by Christians (probably is, as it is American </sacarsm>), but it did spell out the principle:

The first topic that needs to be considered is whether investing is or is not scriptural. As in many cases, the answer depends on the situation. Anyone investing because of greed (Luke 12:15), to get rich quick (Proverbs 23:4-5), or to massage his ego (Proverbs 29:23) is not participating in biblically-based investing. On the other hand, those who are acting as good stewards as in Luke 19:12-27 or those who are saving for future needs such as college or retirement (Proverbs 6:6-8) are participating in biblical investing. In the end, it all depends on the attitude, which is ultimately determined by God. Remember, "All a man's ways seem innocent to him, but motives are weighed by the Lord." (Proverbs 16:2).

Not sure why it has omitted the most obvious reference:

Matthew 6:24 (ESV) No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.

Luke 19 seems to have been used outside its context, where Jesus was about to enter Jerusalem, and told this parable to address their disciples' misunderstanding on the coming of the Kingdom of God (Luke 19:11). Being a good steward in Luke 19 is not about investing money wisely and "grow your net worth" in this age.

On the other hand, Proverb is full of messages encouraging its audiences to be prudent, not to be lazy, and other principles of "good living". Cash Value of Matthias Media has a nice chapter on Proverb and prudence. Here's an extract:

All the same, lest we think that Provers is endorsing some kind of capitalist work ethic, we should also note the 'take it or leave it' attitude Proverbs displays towards wealth... Proverbs is also quick to point out that wealth has its limitations and disadvantages.

Especially with Agur's words,

Proverbs 30:7-9 (ESV) Two things I ask of you; deny them not to me before I die: Remove far from me falsehood and lying; give me neither poverty nor riches; feed me with the food that is needful for me, lest I be full and deny you and say, "Who is the LORD?" or lest I be poor and steal and profane the name of my God.

Joshua will give 3 sermons on Proverbs later next month. Looking forward to them.
