Back to the OP,
C.H. Spurgeon on that parable (sermon of August 1, 1858):
" 'No', says one strong-doctrine man, 'God never invites all men to himself; he invites none but certain characters.' Stop, sir, that is all you know about it. Did you ever read that parable where it is said, 'My oxen and my fatlings are killed, and all things are ready: come unto the marriage'. And they that were bidden would not come. And did you never read that they all began to make excuse, and that they were punished because they did not accept the invitations. Now, if the invitation is not to be made to anybody, but to the man who will accept it, how can that parable be true? The fact is, the oxen and fatlings are killed; the wedding feast is ready, and the trumpet sounds, 'Ho every one that thirsteth, come and eat, come and drink'. Here are the provisions spread, here is an all-sufficiency; the invitation is free; it is a great invitation without limitation. 'Whosoever will, let him come and take of the water of life freely'."
