It scarcely makes sense that God would have made creation "proclaim His glory" and that all would be "without excuse" if sin had hardened us past the point of seeking Him. I believe all humans possess the sensus divinitatis (innate sense of the divine) and ability to seek God. I also believe that God calls and convicts individuals, perhaps numerous times in the course of a life. We are still responsible for how we exercise our free will in responding. I see no dichotomy in believing we all have the ability to seek God but God must call and convict.
Nobody could seek God, that is proven, as men seek the devil ( selfishness, pride and pleasure)
God calls men out of that darkness ( by the Gospel) but the condemnation was told, men love darkness rather than light ( STILL)
Romans 3:10 As it is written, There is none righteous, no, not one:
11 There is none that understandeth, there is none that seeketh after God.
12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
14 Whose mouth is full of cursing and bitterness:
15 Their feet are swift to shed blood:
16 Destruction and misery are in their ways:
17 And the way of peace have they not known:
18 There is no fear of God before their eyes.
19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
John 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
