Materialism can cause us to become distracted and neglect our shield of faith. The apostle Paul said: “No man serving as a soldier involves himself in the commercial businesses of life, in order to gain the approval of the one who enrolled him.” (2 Tim. 2:4) In fact, Roman soldiers were not allowed to get involved in any trade. Like good soldiers, we do not become distracted from our primary goal​—gaining the approval of our Commanders, Jehovah and Christ. We view that as being more valuable than gaining anything Satan’s world has to offer. We make sure that we have the time and energy we need to serve Jehovah and to keep our shield of faith and the rest of our spiritual armor in good condition. We must never let down our guard! Why? The apostle Paul warned that “those who are determined to be rich” will be “led astray from the faith.”​—1 Tim. 6:9, 10. w19.11 17 ¶12, 14-15
