There is a doctrine out there which is dangerous. It is based to a certain extent on the proverbs, and on natural law. The Proverbs and Natural Law remind us that we reap what we sow. If we do not exercise, we become unfit. If we do not practice a craft or discipline, we fail to improve. If we spend impulsively and recklessly, we will be poor.
And if we chase wealth and happiness we will be disappointed.
1 Timothy 6:6-21
6 Of course, there is great gain in godliness combined with contentment; 7 for we brought nothing into the world, so that we can take nothing out of it; 8 but if we have food and clothing, we will be content with these. 9 But those who want to be rich fall into temptation and are trapped by many senseless and harmful desires that plunge people into ruin and destruction. 10 For the love of money is a root of all kinds of evil, and in their eagerness to be rich some have wandered away from the faith and pierced themselves with many pains.
11 But as for you, man of God, shun all this; pursue righteousness, godliness, faith, love, endurance, gentleness. 12 Fight the good fight of the faith; take hold of the eternal life, to which you were called and for which you made the good confession in the presence of many witnesses. 13 In the presence of God, who gives life to all things, and of Christ Jesus, who in his testimony before Pontius Pilate made the good confession, I charge you 14 to keep the commandment without spot or blame until the manifestation of our Lord Jesus Christ, 15 which he will bring about at the right time—he who is the blessed and only Sovereign, the King of kings and Lord of lords. 16 It is he alone who has immortality and dwells in unapproachable light, whom no one has ever seen or can see; to him be honor and eternal dominion. Amen.
17 As for those who in the present age are rich, command them not to be haughty, or to set their hopes on the uncertainty of riches, but rather on God who richly provides us with everything for our enjoyment. 18 They are to do good, to be rich in good works, generous, and ready to share, 19 thus storing up for themselves the treasure of a good foundation for the future, so that they may take hold of the life that really is life.
20 Timothy, guard what has been entrusted to you. Avoid the profane chatter and contradictions of what is falsely called knowledge; 21 by professing it some have missed the mark as regards the faith. Grace be with you.
I am referring to the prosperity doctrine. If one does what is good, one will get a good result.
This is a partial teaching, because the times are uncertain, and we do not live alone. We can do everything well and properly and be swept up in a depression or war, or persecution. We can be preserved from all that but be struck down by illness.
This world is orderly enough that most of the time being prudent, humble and hard-working will lead to one reaping benefits for their family and themselves. But that has never been guaranteed. Paul tells young men to pursue righteousness. For riches, although good (it is better to have some money than none) can be a trap.
