I have noticed a parallel - one that I find mystifying - among the cults, that they all hate the doctrine of the perseverance of the saints. Whether Rome, or the Mormons, or the Watchtower, or the Oneness
The doctrine of perseverance is taught all though Scripture, in both testaments. I give a New Testament example above. In the Old Testament we have, for example, this example from the words of David (Psalm 145:20): "The Lord preserves all who love Him, but all the wicked He will destroy."
One thing I immediately notice that distinguished David from the cultists is that he puts his trust in God for perseverance. There is no priest, pope, governing body, or juvenile elder, standing between him and God. His trust is neither in a man, or trusting in a man's assistance or words, but only in the promise of God. God alone.
One of the slanders that Arminians use against Calvinists is that we depend on the doctrines of a man instead of the Bible. However, while Calvin was certainly a man, it is in the Bible alone that Calvinists look for truth. Would it be fair for me to point out that the Arminian also bears the name of a man, Jacobus Arminius, and claim that they, therefore, find their doctrines in the words of a man? Of course not. Nor would I point to the doctrine that they have in common with pseudo-Christian cults and claim that they, therefore, are cultists.
Rather, let us look to what the Bible teaches. I think that a dispassionate consideration can only conclude that it is the Calvinist who is consistent with Scripture.
And I am very happy with that conclusion!
