It may be hard to think sometimes but He is there for us always. We all go through hard times and hit some rough spots in our lives. We might not feel that God is with you in those times. I've heard this quote a few times before but it goes a little something like this; "God does not promise you a trouble-free life. He does not answer all the questions you may have about life or everything in between. But what He does promise is that He will be there with you through your times of trouble".
So.. Just keep your trust in God. Our understanding of things doesn't even compare to His.
