I have always been mystified why ID advocates get snippy when you question the competence of the designer.
I believe that your contention is the following: How does the Bible reconcile God’s goodness and power with the presence of evil, sin, and suffering? Logically there is only one way to reconcile these two statements without denying any element in them: There must be a source of sin outside God.
God is good and created a perfect world. But the one of the things that makes humans intelligent beings is freedom. They have the freedom to turn away from God or to obey him. And to turn from God, the source of all goodness, is to create evil. Evil does not have an independent existence, nor was it created by God. Evil was created by sin.
Your next question: If God is omniscient, why would he create such a mess? In order for God to ensure that we could not sin, he would have to tamper with our freedom…..to create us not as full beings but as robots programmed to do what he wanted. Knowing this would only make us incapable of loving God or loving one another, for genuine love cannot be coerced. Also, without free will, we would not be capable of moral responsibility, creativity, obedience, loyalty, or heroism. Thus, the only way God could create beings that are truly human was to take the risk that they would use their freedom to choose evil.
Your post is irrelevant. ID is presented as a scientific theory, not as part of a religion.
I have aske for months for any ID advocate to discuss the methods and motives of the designer, and I have been assured that ID says nothing about the identity or motives of the designer.
