An observation: God doesn’t seem to be a person in this theology, more like an inexorable force. The way I see it, genuine love only exists between persons, so I don’t see how “God loves me” is true with this theology.
God is a Person, or rather, a communion of Three Persons distinct in their relations, but one in substance. Each perfect, holy, eternal, infinite and unlimited. This cannot be proven philosophically, but it is a theological truth. Of course, you are free to accept or not accept this.
Christian Scriptures imply that God will one day “do violence” to human and angelic free will with a burning lake of fire. If God will one day punish injustice despite free will presently existing, why doesn’t he do this sooner?
Yes, that is true, although not in the sense that you imply it. Freedom implies choice but it also involves responsibility. God respects the freedom and autonomy of rational creatures. Every rational creature is free to believe or not to believe, this in fact is at the origin of Evil. God created rational creatures free so that they could enjoy His perfect freedom and be happy with Him. After their Fall, the fallen angels were cast out of Heaven and bound in Hell, which is the state of eternal separation with God although it also comprises darkness and the subjection of the angelic spiritual essences to a physical fire, that torments them.
In this, is seen the fact that although God is Love, and Goodness, He is also Just. He does not leave Evil unpunished, or else it would involve a contradiction of His Goodness and of His Providential rule over creation. Now you ask why God does not sooner punish injustice. By this, I surmise that you mean, why doesn’t God end all injustice all at once? I am not certain on this. One reason is that, as stated earlier, God respects human freedom, human autonomy, and its consistent inclination towards rebellion to God and His Law. The root cause of sin and injustice, is the lack of consideration of God, as the ultimate end of man’s rational existence. Man is essentially a fallen creature. God cannot put an end to moral evil because it would involve doing “violence” to man’s freedom. In order for God to put an end to evil, man has to want God, worship Him and recognize the necessity of His existence. Keep in mind that according to Christian theology, human evil cannot be separated from the struggle between the forces of God, and the forces of Satan. The reason why God has not put an end to evil, it is because mankind has not yet reached “the fullness of the stature of Christ”. Now, we cannot expect all of mankind to convert to Christianity as a whole. In fact, if Scripture is correct, the historical cohabitation between good and evil will end in a virulent and methodical persecution of the Christian people. Still, this persecution of cosmic ramifications, will help regenerate humanity, that is, redeemed Christians, to achieve the maturity of Christian spirituality. It is only by this realization that mankind will have reached the perfect adoration needed to put an end to the existence of both moral and natural evil. Now, the reasons I have stated are essentially theological.
What greater good comes from a little child in African dying from starvation or disease?
I do not know. In fact, there isn’t. This is why all Christians should do their best to improve humanity’s material condition and assist in the alleviation of suffering. The Church has done a great deal of good in this matter. And within the history of Christianity, and of Christendom, many of the hospitals were originally founded by religious orders in order to assist in the care of the sick and the destitute.
Still, your insistence on the existence of suffering as an absolute aberration and an insult to human dignity stems in my belief from your incapacity to accept the simple truth that all evil results from the sin of man, of his imperfection, and the fact that in most instances God cannot directly intervene in order to right human injustice. Rather, He tends to make use of human intermediaries to carry the works of goodness. This is called divine Providence. But, once again, it must be stated, God respects the autonomy of human earthly life. In fact, all creation contains its own autonomy, its own laws, a network of physical causes built one upon the other. This principle of causality is even admitted in Buddhism. But in the end, all this chain of different causes are put into motion by the First Cause, who is the Origin of the universe and who maintains all reality into being. As such, the orderliness of the universe is itself the reflection and the expression of God’s creative activity.
