Can there really be a God with all this suffering around?

A question that has been asked through the ages. We look around us and see relatives suffering in pain with illnesses, a child cut short in the prime of life due to some accident, a earthquake killing thousands, an evil murderer living a full and happy life on some island. We see divorce, brokeness and economic problems. We say how can there be a God, if there was a God he wouldn't ignore all this or do nothing about it surely, maybe there is a God but he doesn't care, maybe he is distant, maybe he is angry and is letting us mess it up. Whatever stage you are at with this it is a big question. If you are asking the question in order to show there is no God I beg to differ, and please hear me out.
If you suppose there is evil in the world, ie. suffering. In order for us to know it is wrong or unjust or evil we must have something to measure that against, a good, otherwise how would we know it is evil. If there is a good and there is an evil then there must be a standard by which we can measure that, if there is a standard there must be a standard giver, ie a God and therefore the question refutes itself. Let me put it another way, the very fact we are outraged at suffering (rightly so) shows us that something is indeed wrong, if the world was a mere chance encounter, humans around by shere chance and then we have no leg to complain. If there is a God then we begin to ask why, the fact however that there is suffering doesn't negate there being a God, it points us to him!
When I ask the questions of suffering I have found only one belief system with an answer to it, most systems either deny it, i.e. atheist, or other faiths say that God is punishing and needs to be appeased. Only in Christ do I see a God that not only gives a reason for suffering, that man willfully turned away from its creator and brought the disease of suffering in but that the same creator entered into that suffering and suffered himself, being subjected to the worst suffering any human can suffer the full weight of God, the death upon the Cross was bringing you to a place where if you accept God will take you out of suffering finally at your death when he will wipe away every tear...

You can't really know...

Recently I have heard several people say this to me, "we cannot really know what's true, we cannot trust what we are told" - I totally understand that this is how life appears, I was in the same boat some years ago thinking how can you possible know what's true, there is no way of knowing, you cannot know the truth. Then someone kindly pointed out to me that I thought that statement that I had made was very true, that I sincerley believed the truth of what I was saying and I was living out my life accordingly! It hit me in the face, although that statement that we can't really know anything sounds so plausible, nothing else in my life lived up to that. It is what philosophers call a logical fallacy, logically it doesn't play true anywhwere else in life.
We can know the truth, we examine the evidence and we make up our minds. Don't hold that examination off like I did, I emplore you!
