Christianity professes conviction from the Holy Spirit according to the Bible. The only way to know God in Christianity is through the Holy Spirit. That comes through hearing the word of God preached. According to the bible it becomes obvious to all who hear the word of God. For if they do not know God's truth no one could be yet held to a final judgment. According to Christianity all will know what they conscientiously reject or accept. Iow, they'll know the truth irrefutably, and reject it. Free will dictates that all must know the truth in order to accept or reject it. So those who reject the truth will know they reject the actual truth.
And that is the Bible.
So in conclusion conviction only comes through the Holy Spirit, and those who hear are without excuse because they know that they know that they know the truth and reject it.
All the evidence in the world won't matter without the Holy Spirit.
As an atheist I know no such truth. That is my honesty. I know the Bible salvation message accurately and still have no conviction of it's truth. So either Christianity is false, or the Holy Spirit has yet to convict me. Until I know it's true there is no free will choice.
Well if you are going to say what's in the Bible, you can't be picky. Otherwise, you misrepresent the truth, and don't show interest in truth.
Hopefully the latter is not the case.
(Romans 1:18-23)
18 For God’s wrath is being revealed from heaven against all ungodliness and unrighteousness of men who are suppressing the truth in an unrighteous way,
19 because
what may be known about God is clearly evident among them, for God made it clear to them. 20 For his invisible qualities are clearly seen from the world’s creation onward, because they are perceived by the things made, even his eternal power and Godship, so that they are inexcusable.
21 For although they knew God, they did not glorify him as God nor did they thank him, but they became empty-headed in their reasonings and their senseless hearts became darkened.
22 Although claiming they were wise, they became foolish
23 and turned the glory of the incorruptible God into something like the image of corruptible man and birds and four-footed creatures and reptiles.
(Psalm 19:1, 2)
1 The heavens are declaring the glory of God; The skies above proclaim the work of his hands. 2 Day after day their speech bubbles forth, And night after night they reveal knowledge.
Hence...
(Psalm 10:4)
In his haughtiness, the wicked man makes no investigation; All his thoughts are: “There is no God.”
Then, alongside that, we have this.
(1 Thessalonians 2:13) . . .when
you received God’s word, which you heard from us, you accepted it not as the word of men but, just as it truthfully is, as the word of God, which is also at work in you believers.
Examining the Bible, reveals this to be true.
(Joshua 23:14) . . .
not one word out of all the good promises that Jehovah your God has spoken to you has failed. They have all come true. . .
We have two primary sources of physical evidence where we find hundreds of pieces of evidence.
The holy spirit comes into play, only where the humble - not the haughty, or arrogant deniers - act on the evidence before them.
In other words, they don't squeeze their eyes shut, or stick their head in the sand.
That's what Jesus was referring to in
Matthew 13:10-16
