When Samson was born, the Philistines were ruling over the nation of Israel and oppressing it. (Judg. 13:1) Their harsh rulership brought great suffering to the Israelites. Jehovah chose Samson to “take the lead in saving Israel out of the hand of the Philistines.” (Judg. 13:5) To fulfill this challenging assignment, Samson would have to rely on Jehovah. On one occasion, a Philistine military force had come to capture Samson at Lehi, evidently in Judah. The men of Judah were afraid, so they decided to hand Samson over to the enemy. Samson’s own people bound him securely with two new ropes and brought him to the Philistines. (Judg. 15:9-13) However, “Jehovah’s spirit empowered” Samson and he freed himself from the ropes. He then “found a fresh jawbone of a male donkey,” picked it up, and used it to strike down 1,000 Philistine men!​—Judg. 15:14-16. w23.09 37:3-4

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
