14, 15. What will help us not to be affected by the negative speech of others?

¹⁴ Do not allow negative speech to affect you. The Israelites in Moses’ day had ample reason to believe that Jehovah would successfully usher them into the Promised Land. (Ps. 78:43-53) But when faced with the negative report of the ten unfaithful spies, they did not “remember his hand.” (Ps. 78:42) If we meditate on Jehovah’s activities, remembering all the good things he has done for us, we will strengthen our relationship with him. As a result, we will not allow the negative ideas of others to drive a wedge between us and Jehovah.​—Ps. 77:11, 12.

22, 23. What should we remember if we become discouraged because of our problems?

²² When you are undergoing hardship and difficulties, remember the example of Joshua and Caleb. Unlike the ten other spies, these two faithful men brought back a positive report. (Num. 14:6-9) They showed faith in Jehovah. Even so, they had to wander in the wilderness for 40 years along with the rest of the Israelites. Did Joshua and Caleb complain or become bitter, feeling that this was unfair? No. They trusted in Jehovah. Were they blessed? Absolutely! Whereas a whole generation died in the wilderness, both of these men eventually entered the Promised Land. (Num. 14:30) Similarly, we will receive Jehovah’s blessing if we do not “tire out” in doing his will.​—Gal. 6:9; Heb. 6:10.
