You do know that if God wanted to He could in an instant cause you to have ambition to not only want the promotion, but also through some means to give you that promotion? I think it's important that YOU think you're lazy.
Sometimes it's real tough for me to trust God when I find myself in similar situations as you and I don't always come shining through. It could be one of them "training tactics" God uses to get us to see something about ourselves that needs changing, like learning to trust that He knows what He is doing and is always in complete control no matter what it seems like.
Don't forget Pharaoh and then Israel in the desert, how God hardened their hearts.
Rom 9:15 For He tells Moses: I will show mercy to whom I show mercy, and I will have compassion on whom I have compassion.
Rom 9:16 So then it does not depend on human will or effort, but on God who shows mercy.
Rom 9:17 For the Scripture tells Pharaoh: For this reason I raised you up: so that I may display My power in you, and that My name may be proclaimed in all the earth.
Rom 9:18 So then, He shows mercy to whom He wills, and He hardens whom He wills.
Heb 3:7 Therefore, as the Holy Spirit says: Today, if you hear His voice,
Heb 3:8 do not harden your hearts as in the rebellion, on the day of testing in the desert,
Heb 3:9 where your fathers tested Me, tried Me, and saw My works
Heb 3:10 for 40 years. Therefore I was provoked with this generation and said, "They always go astray in their hearts, and they have not known My ways."
Heb 3:11 So I swore in My anger, "They will not enter My rest."
Heb 3:12 Watch out, brothers, so that there won't be in any of you an evil, unbelieving heart that departs from the living God.
