How Do You See God?
Your perception about God is very important. This is because how you perceive Him will determine how He will also manifest Himself to you. If you doubt He's s ability to do exceedinly and abundantly then His power to do will be very limited in your life.

Many people have compounded their problems becuase of how they see their problems, they keep worrying and make their problems seems bigger than the big God they serve.
Instead of them to look up to God first they rather consider their problems first and by pondering over them make them grand in their eyes.
God is is bigger than the biggest and stronger than than the strongest. He is above everything that man sees to be insurmountable.
He is capable and able of doing anything he promises. Often times people receive no manifestation from God because of how they see Him.
In Him there are no impossiblities but hope, and assurance of whatever he promises. For God to manifest Himself to you, then you must change how you see Him.
Before the doctors tell you that sickness will eventually lead you to death first look to God who is the master healer. Avoid condering or accepting any negativity that will virtually make you see God as smaller.
Focus on a big God and Not a big problem
You said it all , God is always bigger than what we think He is and bigger than your problems you are facing .
I have no doubt that God is absolutely sovereign over his entire universe. We should pray when we have troubles. We know that God can do anything yet at times he doesn't remove the thorn in our flesh. In my case, my first wife died when she was 30 and our two children were both stillborn.
This is indeed sad, I believe it hasn't been easy going through this experience but in all God knows best. I'm sorry for your loss. God works in ways we cannot see and sometimes it very hard to know what He's up to. The only thing we can do is to keep trusting Him even if we going through the worse. I believe He wait till the last minute when we cannot carry on then He steps in so we will understand that He is the God of possibilities and He iscapable of turning things around even at the last minute.
Thanks @collinx..., God is great God and cannot be compared with any being!
