Study God’s Word and meditate on it. Just as a tree can stand strong if it has deep roots, we can remain firm if our faith is deeply rooted in God’s Word. As a tree grows, its roots grow deeper and spread farther. When we study and meditate, we strengthen our faith and deepen our conviction that God’s ways are best. (Col. 2:6, 7) Reflect on how Jehovah’s instruction, guidance, and protection helped his servants in times past. For example, Ezekiel paid close attention as an angel took detailed measurements of the visionary temple. This vision strengthened Ezekiel, and it provides us with practical lessons about how we can uphold Jehovah’s standards for pure worship. (Ezek. 40:1-4; 43:10-12) We also benefit when we take time to study about and meditate on the deeper things of God’s Word. We can have a steadfast heart, trusting fully in Jehovah.​—Ps. 112:7. w23.07 18 ¶15-16

The Bible is filled with good examples for young men to imitate. Those men from the past loved God and handled various responsibilities in caring for his people. You can also find good examples among the mature Christian men in your own family and in your congregation. (Heb. 13:7) And you have the perfect example of Jesus Christ. (1 Pet. 2:21) As you carefully study these examples, consider their outstanding qualities. (Heb. 12:1, 2) Then decide how you will imitate these men. A man with thinking ability considers his options carefully before acting. So work hard to gain and maintain that ability. Begin by learning Bible principles and thinking about why these are beneficial. Then use those principles to help you make decisions that will please Jehovah. (Ps. 119:9) That is a major step toward becoming a mature Christian man.​—Prov. 2:11, 12; Heb. 5:14. w23.12 24-25 ¶4-5

Parents can effectively teach their children how to respond mildly when their beliefs are challenged. (Jas. 3:13) Some parents have practice sessions during family worship. They consider topics that might come up at school, discuss and demonstrate how to give an answer, and teach their children how to speak in a mild, appealing way. Practice sessions can help Christians to present convincing arguments and to convince themselves that they have sound reasons for their beliefs. The “Young People Ask” series on jw.org includes worksheets for teenagers. Those are designed to help young ones to reinforce their beliefs and to prepare answers in their own words. By studying this series as a family, we all can learn how to defend our faith in a mild, appealing way. w23.09 17 ¶10; 18 ¶15-16
