Fully Trusting

Today I have a very big test I'm taking...and I have to admit - I'm not too excited about it. Namely, because I'm worried I'm going to get a bad grade, which is not good. So I'm just trying to trust that whatever happens with this test, it will work out for the good no matter what. I am just trusting in God.
Do you have those times in your life where you just feel like you can't trust God? Where you just feel like..."He's messed up things before! I can handle this myself.". First of all, if you have...God does NOT mess things up. It's all simply a part of his plan for your life. He has a purpose and a reason. Secondly, you may think you can handle it your self, but in reality...YOU CAN'T HANDLE ANYTHING WITHOUT GOD. Seriously, admit it. When we try to do things by our self without our Father's help...things get extremely messy, and there's also consequences! So next time you think you will be fine without His help, remember this - you wont' be.
Trusting in God requires faith. You can't trust God if you don't have faith in Him. Too many times Christians just flat out forget about having faith in Him. He's the only reason we are here, He gave us what we have, so why wouldn't we have faith in Him? Plus, if we put our faith in anything or anyone else, our lives will be miserable, 100% possitive. So have faith in God, and stop putting other things or people above him on your priority list, because things will only get worse if you do.
The bible says "Trust in the Lord with all your heart and lean not unto thine own understanding". What do you think this says? Well it is basically what I just was talking about a minute ago. We need to stop trying to handle things on our own (leaning on our own understanding) and put our trust in God with our whole heart - not just part of it. That's another thing believers struggle with. Fully trusting in God with your whole heart can be challenging, especially during really hard times in your life. So many times we give him a little bit of our heart, but then hold back the other piece. If you do that, you are basically holding back a burden that the Lord could take from you to give you some peace. But too often we keep holding on and won't let go. The right thing to do is give that other piece of our heart and put it all in the hands of God, because He controls everything anyway.
Trust in God. Don't hold your trust back. He wants your heart and mind fully relying on Him at all times, no matter what the circumstance.
