"From the biblical answer flow four important facts.
Firstly, the God who is there is a good God.
Secondly, there is a hope of a solution to the dilemma of man.
Thirdly, there is a sufficient basis for morals. 
Nobody has ever discovered a way of having real “morals” without a moral absolute.
 If there is no moral absolute, we are left with hedonism (doing what I 
like) or some form of the social contract theory (what is best for 
society as a whole is right). However, neither of these alternatives 
corresponds to the moral motions that men have. Talk to people long 
enough and deeply enough, and you will find that they consider some 
things are really right and some things are really wrong.  
Without 
absolutes, morals as morals cease to exist, and humanistic man starting 
from himself is unable to find the absolute he needs.  But because the 
God of the Bible is there, real morals exist.  Within this framework I 
can say one action is right and another wrong, without talking nonsense.Fourthly,
 there is an adequate reason for fighting wrong.  The Christian never 
faces the dilemma posed in Camus’ book La Peste.  It simply is not true 
that he either has to side with the doctor against God by fighting the 
plague, or join with the priest on God’s side and thus be much less than
 human by not fighting the plague. If this were an either-or choice in 
life, it would indeed be terrible. But the Christian is not confined to 
such a choice.  Let us go to the tomb of Lazarus.  As Jesus stood there,
 He not only wept, but He was angry.  The exegesis of the Greek of the 
passages John 11:33 and 38 is clear. Jesus, standing in front of the 
tomb of Lazarus, was angry at death and at the abnormality of the world 
the destruction and distress caused by sin.  In Camus’ words, Christ 
hated the plague.  He claimed to be God and He could hate the plague 
without hating Himself as God.
A Christian can fight what is 
wrong in the world with compassion and know that as he hates these 
things, God hates them too.  God hates them to the high price of the 
death of Christ.But if I live in a world of nonabsolutes and
 would fight social injustice on the mood of the moment, how can I 
establish what social justice is?  What criterion do I have to 
distinguish between right and wrong so that I can know what I should be 
fighting?  Is it not possible that I could in fact acquiesce in evil and
 stamp out good?  The word love cannot tell me how to discern, for 
within the humanistic framework love can have no defined meaning.  
But
 once I comprehend that the Christ who came to die to end “the plague” 
both wept and was angry at the plague’s effects, I have a reason for 
fighting that does not rest merely on my momentary disposition, or the 
shifting consensus of men.But the Christian also needs to be
 challenged at this point.  The fact that he alone has a sufficient 
standard by which to fight evil, does not mean that he will so fight.  
The Christian is the real radical of our generation, for he stands 
against the monolithic, modern concept of truth as relative.  But too 
often, instead of being the radical, standing against the shifting sands
 of relativism, he subsides into merely maintaining the status quo.  If 
it is true that evil is evil, that God hates it to the point of the 
cross, and that there is a moral law fixed in what God is in Himself, 
then Christians should be the first into the field against what is wrong
 — including man’s inhumanity to man."
