Jehovah can become whatever is necessary in order to accomplish his purpose. For instance, Jehovah has become a Teacher, a Comforter, and an Evangelizer, just to name a few of his many roles. (Isa. 48:17; 2 Cor. 7:6; Gal. 3:8) Still, he often uses humans to carry out his purposes. (Matt. 24:14; 28:19, 20; 2 Cor. 1:3, 4) Jehovah can also give any of us the wisdom and strength we need in order to become whatever is necessary to fulfill his will. This is all part of the meaning of Jehovah’s name, as it is suggested by a number of scholars. All of us want to be useful to Jehovah, but some may doubt that Jehovah is using them. Why? Because they feel limited by their age, circumstances, or abilities. On the other hand, others may be quite satisfied with what they are already doing and fail to see the need to make further progress. w19.10 20 ¶1-2
