This is such an insight, I remember the eye opening importance of remembering those passages of Scripture and the value of them while contending for the faith with non-believers. Romans Chapter 1:18-32 also helped shed light, from it we see that non-believers do believe, but suppress that knowledge, and in the process deceive themselves to the point of believing the lie concerning the existence of God. Which is why all the empirical proof in the world would not convince them. And if we take a further look in Scripture, concerning non-believers we read..
The non-believer is dead in sins and trespasses (Eph 2:1), and does
not want interaction with the true God of Scripture.
1 Cor 2:14 -
But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned.
Jn 14:16-18 - And I will pray the Father, and He will give you another Helper, that He may abide with you forever, even the Spirit of truth, whom the world cannot receive because it neither sees Him nor knows Him
Jn 3:18-21 - He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
Romans 8:5-8 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit, the things of the Spirit. 6 For to be carnally minded is death, but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. 8 So then, those who are in the flesh cannot please God.
Not only do they not want the truth (Jesus), but cannot the receive things of the Spirit of God, nor please God.
However, because we do not have certain knowledge of who is elect or not among us, we are like farmers sowing seed, while God gives the growth or not.
