I'm a little confused by something here, webmaster.
First off, you quoted the statement David made about the passage in Jude, but the you didn't respond to it - you completely ignored it. What's up with that?
Second, you say that the Tares and the Wheat both receive the Gospel. As I read the parable, that's not the conclusion that I come to at all. First off, you're wrong in saying that the seed (implying, all the seed) is the Gospel. The parable is clear that the sower sows good seed while the enemy sows tares (vss. 24 and 25). So there are two types of seed - good seed and tares. The good seed, and the good seed alone, is the Gospel. The tares are sown by the enemy, and they represent that which is not the Gospel. The tares do not receive the good seed, because the tares weren't there when the good seed was sown. Only the wheat receives the Gospel, and only the wheat are saved, and there is no mention of those that have received the gospel then turning around and rejecting it (a wheat turning into a tare).
In the explanation of the parable by Jesus, you're missing one big thing. The tares and the wheat are not what is doing the receiving - the field is. The field is the world. The world produces two fruits, then - wheat and tares; christians and non-christians. Nowhere in the parable or the explanation of it is there any hint of a wheat turning back into a tare. Interestingly, there is also no hint of a tare turning into a wheat - which I believe is symbolic of the fact that the elect of God were chosen before the foundation of the world.
I'd be interested to hear your commentary on the parable, as opposed to mine. You can post the verses all you want, but I'd like to know how you get from the verses to what you believe.
