Surrendering

"Come to me with all your weaknesses; physical, emotional and spiritual. Rest in the comfort of my presence,  remembering that nothing is impossible for me." ~ Feb. 15th meditation in "Jesus Calling," by Sarah Young

I keep struggling with the same weakness and don't seem to be able to make any progress, despite my "alleged" determination to make progress.

Alleged is in scare quotes because the level of determination on my part varies greatly, depending on my comfort level with any sacrifice that might be required.

So, when I read a meditation like the one quoted above, I wonder if I am going about it all wrong? How do I surrender those areas of most concern to me?

Those areas that I want to be good at but am clearly not?
I think I have surrendered them, but when I realize how little progress I am making, I clearly have not relinquished control.

Part of the reason is that I want those areas of my life to be better before I let  God take control, I guess.

For some reason, these weaknesses seem so petty that I am sure God doesn't want to be bothered with them.

Yet, if He wants all of me, it should include those deepest weaknesses, shouldn't it?

Or perhaps, in reading Ephesians 3:20-21, it is a failure of imagination on my part to be able to grasp what God desires of me and for me.
Lord, my God and Savior. Please help me. You know what I need. You know my deepest failures and embarrassments. You know my desires, which maybe are not your desires for me. Please show me what you desire for me and then help me to get there.
Thank you.
