I see this accusation from both side of discussions, but isn't there a clear distinction in someone who doesn't understand a truth and someone who understands but rejects it?
Indeed there is, as one can be "ignorant" to what the Bible teaches on a subject, disregard to what it actually teaches, or else have a different interpretation on what is being taught...
Think that a lot of this question hinges on how one understands the nature of the Fall of man thruAdam...
if you hold to doctrine of original Sin, we have a sin nature, and that the Fall so 'destroyed" image of God in us as due to that...
One tends to be a Calvinist
if you tend to see it as being that the fall "marred" us, no sin nature, still have free will, that God has granted to all men a "measure" of grace/faith to believ, tends to be an Arm...
So basically different starting points, so different interpretations at times from same verses!
The same point can be made regarding ones understanding of the gospel. Some argue that only the elect can understand the gospel, but what is meant by that exactly?
that unless the Holy spirit does His work to convict of Sin, need to have a Saviour, and that He allows one to become quickened to receive Gospel, repent receive believe, they will stay dead in sins and trespasses..
Not saying the "natural" Fleshy person cannot gear the Gospel, its just that without the Lord revealing it to them, and by His act of grace "openning" them up to be able to receive it and respond to it, will just stay words to them, they will not turn and be saved...
Does that mean they really can't understand the clear words of the gospel appeal, or does it mean they just can't willingly follow once they do understand it?
they will be able to understand in sense that the devel and demons know there is a god, jesus is His Son, but will not able to receive Him as that, as their natural sinful nature will not submit to the truth in the Gospel...
Willfully choose to stay in darkness, as will read and understand, but refuse to heed and obey w/o God directly acting to allow them to do such...
its not that people cannot hear/read/understand the Bible, its just that the sinner cannot apply it to their lives UNLESS there is a direct work/act by God to allow them to believe, as their natural selves cannot receive the things of God,as they are spiritually discerned...
