Sometimes I find myself stuck in a tunnel. I can't see the light behind me or the light before me. I don't know what to do or where to go. I start to get frantic not too sure what to do am I doing the right thing? Am I going the right way? Should I have taken a different path? Why am I alone?
Do you get what I mean somehow? Do you understand what I am trying to say? 

We doubt things and we doubt God. Sometimes I even doubt that I was actually hearing God and I am making things up myself. Sometimes it is hard to tell wether I am hearing God or just me.
It really makes me frustrated with myself sometimes. I just loose my strength and I feel like I am going to give up. Life is hard and it's hard to see where to go. Yet I go back to the Bible and I flip it open.  

Isaiah 40:29-31
He gives strength to the weary and increase the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint. 

God gives us the strength we need to go on and keep on with life and keep up hope so don't give up and trust that God will give you the strength that you need. No matter what, God will give you the strength so keep your head up because he will renew your strength.
