Rhetorical question: No's and Yes's

Have you ever felt like God was telling you No in regards to everything and that no matter what it was or where you looked you always heard, ran into, and saw a NO?!? But then when you least expected it then a YES showed up in the least expected place and in regards to something that you had been waiting for a yes to?!?

God has been telling me NO left and right and no matter what it may be that I was going to do or ask then the answer always showed up to be NO. I couldn't get away from NO's and it has been frustrating. It seemed like God had me drop everything that I had been doing and give it over to someone else and I have not understood the reason behind that until now. After hearing a NO time after time for 2 years in regards to doing God's work He has finally shown up and decided to tell me it's time. 

I have waited 2 years for this and NOW after being half way done with college God has decided to tell me YES?!? I don't understand. he had placed me here on the campus and now after all the waiting and thinking that I was ready 2 years ago to leave all behind and go He tells me yes??? As much as I wish I could do missions for Him, it is becoming reality that I am scared to death and am not ready to give everything up for Him. I want to do it but why now, why after 2 years has He decided to tell me Yes to this question?!? 

I don't know what's going to happen but I am going to be honest and tell you that I am fighting God on this since I am scared to death about what He is calling me to do. I don't know where He wants me to go or what exactly He wants me to do but it's a definite and strong YES that I can't ignore. I don't understand His timing and even if He is saying that it's time and the "training" is done for me to go. I am not sure. I want to trust Him and I do but why a YES now after all that I have been through and hoped to do. Everything is lining up and pointing to it being time but the question is "Am I ready?" and the answer seems to be NO. He has told me NO time and time again and Now a yes shows up. I knew I would fight Him when he would finally say yes but I was not expecting the yes to be directed in this direction and to do this.

So, have you ever been in a similar situation where no matter where you looked and no matter what you asked, God was always telling you No and had you drop everything you had been doing and then out of nowhere you finally get a Yes that you did not expect and then fought God on that decision?? I don't know where God's leading me but the yes is there but I am not sure I am able to go and leave everything when I don't even know where God is leading me to and what He wants me to do.
