A "multiplicity of words" when discussing Owen is a given. Look at the OP. Now read the statement by Owen carefully. What he was saying was exactly the issue that comes up with the hyper-Calvinist wing of this board. Owen was saying, and he goes into it with great detail, that Christ saving who he wants does NOT mean that there is a way for someone to be saved without them doing the very things that God himself has degreed concerning salvation. We have to repent and believe and there is simply no salvation without it because God has so ordained.
According to Owen, and every Calvinist that is not a hyper, God indeed has an elect that is comprised of individuals chosen from eternity past and He will infallibly bring them into salvation in due time. But what happens is that the Holy Spirit will quicken and regenerate, Providence will be in operation working circumstances (like Lydia being able to hear Paul), and the word will be preached, taught or read by the individual so that they can repent and believe - which is essential that they do. That is what Owen is saying. There is room within hyper-Calvinism or Primitive Baptist theology for this exact scenario I know.
But there is also a branch of that where the determinism and election are so emphasized that they actually object to preaching that tells people to repent and believe the gospel. Now this is important: If they say that with the only thing in mind being that an elect person will for sure eventually repent and believe the gospel then that is not a different gospel but it is a different approach. But if you start rebuking people for preaching belief and repentance, or, as some do, you actually start teaching that the determinism is so strong that the elect will be saved even if they never believe or never hear the gospel then THAT is a damnable heresy. I don't know anyone on this board who goes that far but some do go to the point of taking offense at telling someone to ask themselves if they have saving faith or asking them to evaluate their walk. That to me is very dangerous. And it is dangerous because the only warrant you have to really know YOU are elect is by the way you walk and what you believe and Owen thought that with the enlightening and quickening power of the Holy Spirit, such self evaluation was necessary and proper.
