Jesus taught us that no matter how limited our abilities or how small our efforts seem to us as we get older, Jehovah treasures whatever we can do in his service. (Ps. 92:12-15; Luke 21:2-4) So focus on what you can do. You can, for example, speak about Jehovah, pray for your brothers, and encourage others to stay faithful. Jehovah considers you to be his fellow worker, not because of what you accomplish, but because of your willing obedience to him. (1 Cor. 3:5-9) How grateful we are to worship Jehovah, a God who truly values those who serve him! He created us to do his will, and it is true worship that adds real meaning to our lives. (Rev. 4:11) Though the world may view us as worthless, Jehovah is not ashamed of us. (Heb. 11:16, 38) When we feel weighed down by illness, economic hardship, or old age, let us remember that nothing can separate us from the love of our heavenly Father.​—Rom. 8:38, 39. w20.01 18 ¶16; 19 ¶18-19
