The idea brought forth by those who claim that we who hold to God's sovereignty in all things are similar to the Greek pagans is without warranted. As Ronald Nash states in his book The Gospel and the Greeks, these so called gods were limited by their own weakness both physical and moral. Not to mention many of these gods fell into vices in which humans fall prey. See The Gospel And The Greeks, Ronald Nash pg 122.

In contrast the God of Scripture is not limited by his creation but rather is distinct from it and works with in it through the means (Isaiah 46:10-11). Not to mention in Greek thought humans were in some cases even more noble then the so called gods which puts such ideas against the Scriptures which state there is no other God but him (Exodus 20:3; 34:14; Isaiah 44:6. 8, 45:5-6, 21; Hosea 13:4). In addition to put man on equal footing with God is a form of Idolatry (Exodus 20:4; Romans 1:23; Deuteronomy 4:16-17).

Therefore the charge made that the Doctrines of Predestination and Election and our view of God's Sovereignty based on the testimony of Scripture is equivalent to pagan philosophical views of man and God is without merit both on historical, philosophical and Scriptural grounds.
