Plan B but God's got Plan A

I just watched a video about a couple who had lost their child and a book called Plan B by Pete Wilson. Now, I haven't read the book yet but from the messages I have heard and the pieces of the book I have heard here and there I am sure it is a great eye opening, life evaluating book. As I type out this blog I think; does God have a plan B or was this the plan from the get go and I just put in place things that I wanted. Here is where I am going with this.
You see, I am a teacher and I have a test that will determine my job for next year, if I pass the test I keep my job, if I do not pass the test then come June 30th I will be terminated. So, here is what I think. Please don't get me wrong I absolutely love teaching and I love my students; yes even the ones that are or can be ill behaved. I think sometimes why I haven't passed the test I my only response has been because I am stupid. Well, maybe but after this video I am thinking of Plan B maybe this wasn't what God had in-store for me in the first place and I just took a detour of what I wanted to do. Finally God maybe saying "Jenny, you have done what you wanted and I have let you but now Plan B which was really my Plan A needs to come to fruition. I think I have said it before but I do not think I really meant it but I have said "God I need your help and whatever your will" but today I say "God if this isn't your plan A then show me and allow me to have peace with this to know you will take care of me no matter what the results". I do know that you will take care of me and provide for me as you always have, my biggest thing is I need to trust you to the utmost extinct and not think or rely on myself because obviously I will screw everything up. God stand beside me, hold my hand and give me your Plan A and never allow me to look back. I need you more than I have never realized before. I know in the end this will be a lesson learned and I pray that when the lesson is learned you will get the praise and glory from it because you are not a coincidental God but a God of purpose and from the beginning you have had a plan for my life. I want to grab hold of your plan and not mine. I want to walk in your footsteps every step of the way allowing your guidance and your steps to place me where you want me.

Jeremiah 29:11"for I know the plans I have for you," declares the Lord,"plans to prosper you and not harm you and plans to give you hope and a future."
