Jehovah has progressively revealed his “eternal purpose” in the Bible. One way or another, he always succeeds because he “has made everything work for his purpose.” (Prov. 16:4) And the results of what Jehovah does will endure forever. What is Jehovah’s purpose, and what adjustments has he made in order to accomplish it? God told the first humans what his purpose was for them. They were to “be fruitful and become many, fill the earth and subdue it, and have in subjection . . . every living creature” on earth. (Gen. 1:28) When Adam and Eve rebelled, causing sin to enter the human family, Jehovah’s purpose was not thwarted. He adjusted the way it would be achieved. Immediately, he determined to set up a Kingdom in heaven that would accomplish his original purpose for mankind and the earth.​—Matt. 25:34. w23.10 44:6-7

Jehovah can help us to persevere. It may be a struggle to carry on, especially if we are coping with a persistent weakness. At times, our weaknesses may seem more challenging than those that the apostle Peter faced. But Jehovah can give us the strength not to give up. (Ps. 94:18, 19) For example, one brother engaged in a homosexual lifestyle for a number of years before learning the truth. He decisively left those immoral practices behind. Still, he at times struggled with wrong desires. What helped him to persevere? He explains: “Jehovah strengthens us.” He adds: “With Jehovah’s spirit . . . , I have learned that it is possible to [continue] in the way of the truth . . . Jehovah has been able to use me, and despite my imperfections he continually strengthens me.” w23.09 40:12

Young brothers, you will not automatically become a mature Christian man. You need to choose good examples to imitate, develop thinking ability, be reliable, acquire practical life skills, and prepare for future roles. You may at times feel overwhelmed when you contemplate the work ahead. But you can succeed. Remember that Jehovah is eager to help you. (Isa. 41:10, 13) Of course, your brothers and sisters in the congregation will help you too. When you reach your full potential as a mature Christian man, your life will be rich and satisfying. We love you, young brothers! May Jehovah richly bless you as you work now to become mature Christian men. w23.12 53:19-20
