The Society has repeatedly advised Christians to not plan for the long term because the Lord's coming is instead "imminent". They are like the foolish bridesmaids who say, "What's the point of bringing extra oil when the Master is coming any minute?!" They are like the wicked servant who says, "What's the point in trying to invest my Master's money when he is coming any minute to get it back?"
*** w38 11/1 p. 323-324, 332 Fill the Earth Part 2 *** If in obedience to the divine command the Jonadabs or great multitude will marry and rear children after Armageddon, would it not be Scripturally proper for them to begin doing so immediately before Armageddon? and should the Jonadabs now be encouraged to marry and rear children? No, is the answer, supported by the Scriptures. ....It would therefore appear that there is no reasonable or Scriptural injunction to bring children into the world immediately before Armageddon, where we now are.... The resurrected ones, that is, "children of the resurrection," have no [marriage] ties, because death has dissolved whatever marriage relationship existed with reference to them. There is no need, at the resurrection of them, to again take on such marital relationship. They will have nothing to do with the divine mandate to "multiply and fill the earth", which manifestly does not apply to the "children of the resurrection".
*** w67 2/1 p. 81 par. 6 Servants of God Full Time ***
They do not choose to get established in a career in the business world, because they cannot see throwing in their lot with a system that God’s Word plainly says is ‘going out of business’ in the near future. So how do they react to "attractive offers" from the world? During his last year of high school one young brother, just a short time ago, was offered scholarships that would have completely paid for a college education. But he knew that success he might enjoy in the world would be, at most, short-lived.
*** g69 5/22 p. 15 What Future for the Young ***
If you are a young person, you also need to face the fact that you will never grow old in this present system of things. Why not? Because all the evidence in fulfillment of Bible prophecy indicates that this corrupt system is due to end in a few years.... Therefore, as a young person, you will never fulfill any career that this system offers. If you are in high school and thinking about a college education, it means at least four, perhaps even six or eight more years to graduate into a specialized career. But where will this system of things be by that time? It will be well on the way toward its finish, if not actually gone!
*** g74 11/8 p. 11 Is This the Time to Have Children? ***
Today there is a great crowd of people who are confident that a destruction of even greater magnitude is now imminent. The evidence is that Jesus' prophecy will shortly have a major fulfillment, upon this entire system of things. This has been a major factor in influencing many couples to decide not to have children at this time. They have chosen to remain childless so that they would be less encumbered to carry out the instructions of Jesus Christ to preach the good news of God's kingdom earth wide before the end of this system comes.-- Matt. 24:14.
