Question:
Is money management and/or investing taught in the Bible? What is the proper course of action according to God and how much should we concern ourselves with this issue?

Answer:
“He that is faithful in that which is least, is faithful also in much: and he that is unjust in the least is unjust also in much. If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true riches?” (Luke 16:10, 11).

Things of the earth are temporal and therefore “least” when compared to things of heaven, which are eternal. But these verses show that we should also be faithful in temporal things. While exhorted to set our affections “on things above, not on things on the earth” (Colossians 3:2), we should not fail to make prudent use of all that the Lord has entrusted to us now.
We are not given direct written instructions as to how to do this. Better yet, we have the Spirit of God and the mind of Christ (1 Corinthians 2:12, 16). Therefore, as we walk in the Spirit, we become sensitive to the tenor of Scripture, and we are enabled to understand and apply the principles we see there.
[The Lord wants us to be “faithful and wise stewards” of our time, money, and everything He has entrusted to our care (Luke 12:42-44). Here are a few verses that tell us how He wants us to use our money.
(1) As with everything in our lives, the Lord should receive His share of our money first. “Now concerning the collection for the saints….Upon the first day of the week let every one of you lay by him in store, as God hath prospered him” (1 Corinthians 16:2).
(2) We must take care of our own responsiblities. “If any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel” (1 Timothy 5:8).
(3) We are to “Remember the poor” (Galatians 2:10), and when we give, “Let not thy left hand know what thy right hand doeth” (Matthew 6:3).
Interest in the bank of heaven is “an hundredfold” or ten thousand percent (Matthew 19:29)! We cannot take our money with us when we depart this life, but we can send it on ahead.
Also, this will help us to live for Christ now for Jesus said: “Where your treasure is, there will your heart be also” (Matthew 6:21). How we use our temporal things now, also determines our place in Christ’s kingdom in the soon coming day! Isn’t it wonderful that we are able now to bring honor and glory to Him who died for us through the temporal things He has entrusted to our care, and also that this will be the means of our being “blessed” in the glory (Luke 12:43)? The Spirit of God encourages the Lord’s dear people to “Set your affection on things above, not on things on the earth” (Colossians 3:2). Ed.]
