What I feel that it means, it to continue doing good in him, and he will give you what you desire, which if you are doing good in him then your desire will be him. Kinda like in 1Kings chapter 3 vs. 4-14. Basically God was please with king solomon for doing his will so god tells him, "ask for what ever you want, and I will give it to you", all solomon asked for was wisdom to tell right wrong so he could serve god better and help others to as well.

Hope this helps!
