Sin
is our fault, not the fault of the environment, predestination, ignorance
or Satan
God does not wish to send us malady, nor allow it. God does not wish to distress his creatures; if he allows it, it is so that they learn something or as a consequence of some wrongdoing. If God does not wish to send us malaise or distress, but these descend upon us, it is because sin is a human being's doing. Distress can be as natural as a consequence of an act previously committed by us, either as individuals, as a society or as a nation.
“31 For the Lord will not cast off for ever. 32 But though he cause grief, yet will he have compassion according to the multitude of his mercies. 33 For he doth not afflict willingly nor grieve the children of men.” (Lamentations 3:31-33)
Things that happen to man are not always as a result of his action. Sometimes it may be as a consequence of someone else's actions, as in the case in which a child inherits a venereal disease from its parents. We have to understand that what a child inherits is only while in the flesh and he only suffers from it in this lifetime. He may follow God, be saved because of Christ, and live eternally without the inconvenient malady he inherited from his parents, because he will inherit a new body upon his resurrection.
We can say the same about the sin of society, like pornography, whereby children suffer the consequences as well as women who do not participate in that sin. Another case may be the punishment of a nation for allowing abortion. That nation may pay for their sin in the form of war, although many might have opposed abortion, they will suffer the consequences of war.
God does not want to cause man any pain, but if they transgress God's laws, the natural process which follows the lack of obedience is suffered by the entire nation and all of society. Nevertheless, I say, in almost all cases, when a person suffers some form of malady or anguish, it is motivated by a personal act. At least this has been my personal experience.
There are many who wish to blame their sinful tendency and sin to their ancestors. They claim that because Adam and Eve sinned, they have inherited a sinful nature. This is what they refer to as “original sin”. This is false. We explain it in article number 31 of this same website.
