This is the hardest question for any Christian to answer. On the one hand the Bible clearly teaches that ‘God is love’ (1 John 4:8); on the other hand the suffering that we see around us and perhaps even experience at a personal level seems so contradictory to our understanding of that love. It will therefore come as no surprise to know that there are no easy answers to this question. Suffering is no stranger to any one of us, but I believe the Bible gives us both an explanation and also a hope for all of us to take on board.

There are many answers to this questions. First of all, God has given us all free will, that means He will not intervene in any way that stops us having free will, regardless of whether we believe or not. It is because of this free will given to us that the way God mainly chooses to move in the world is through us believers. God requires us to voluntarily move into His will that He is able to work through us. This is so there is a RELATIONSHIP between us and God. Throughout the Bible we can see God constantly working THROUGH people, when each person obeyed, God worked through them. Imagine if Moses didn't obey God at this point-

Ex 14:16
But lift thou up thy rod, and stretch out thine hand over the sea, and divide it: and the children of Israel shall go on dry ground through the midst of the sea.

The Red sea would not have parted if Moses did not do so. This is the relationship we have with God because of our free will. He moves through those who choose to obey Him and therefore become a conduit for God to act. So nothing is just going to just become alright by itself, if we want to make a change, we have to be obediant and open to God so He can work with us.

Second, this world is not the kingdom of Christ, but it is the kingdom of Satan- the 'god' of this world,

John 18:36
Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.

He is the prince of the power of the air, (the air enveloping the earth),

Ephesians 2:2
Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:

Who walks the earth like it is his own lot of land-

Job 1:7
And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.

While we are in this world ruled by the devil, we shouldn't expect it to be a slice of heaven. It rains on the just and unjust alike. The world hates us becaus it hates Christ, which is no surprise considering who its ruler is.

Joh 15:18
If the world hate you, ye know that it hated me before it hated you.

But the devil has no love for any man, woman or child. Which is why they too bear suffering as much as we do. The blood of Christ doesn't cover that which isn't dedicated to God. And we are not guaranteed and to our sufferings, but we can expect that God will give us the strength and courage to endure trials and temptations.

1Peter 2:19-21
For this is thankworthy, if a man for conscience toward God endure grief, suffering wrongfully. For what glory is it, if, when ye be buffeted for your faults, ye shall take it patiently? but if, when ye do well, and suffer for it, ye take it patiently, this is acceptable with God. For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:

James 5:10-11
Take, my brethren, the prophets, who have spoken in the name of the Lord, for an example of suffering affliction, and of patience. Behold, we count them happy which endure. Ye have heard of the patience of Job, and have seen the end of the Lord; that the Lord is very pitiful, and of tender mercy.

2Timothy is a good example of eduring trials as Paul explains to Timothy in his letter, as is Psalm 23, 27 and 28. But we can be assured that this world will come to an end and that the devil has little time left and he knows it. Our trials shall increase and sufferings will mulitply because of it but as the disciples did in Acts let us also be-
"....rejoicing that they were counted worthy to suffer shame for his name. And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ." Acts 5:41-42
