As for seeking, God decides who will find it and who won't. The scriptures are very clear about this, so some seek and go to their grave never finding it.
The problem is, people don't know what they're actually looking for. So how will they know if they've found it. Can I ask what it is you're seeking.
Unless God draws you to Himself and reveals the truth to you, you will never find it.
Matt. 13:10-16
And the disciples came and said to Him, "Why do You speak to them in parables?"
11 He answered and said to them, "Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given.
12 For whoever has, to him more will be given, and he will have abundance; but whoever does not have, even what he has will be taken away from him.
13 Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand.
14 And in them the prophecy of Isaiah is fulfilled, which says: 'Hearing you will hear and shall not understand, And seeing you will see and not perceive;
15 For the hearts of this people have grown dull. Their ears are hard of hearing, And their eyes they have closed, Lest they should see with their eyes and hear with their ears, Lest they should understand with their hearts and turn, So that I should heal them.'
16 "But blessed are your eyes for they see, and your ears for they hear;
The above scripture does tell us that there are some to whom God has given the gift of understanding so they can receive the truth.
While others to whom it has not been given cannot receive the truth or salvation.
So that's what I was trying to say, how can a person know what the truth is unless they have it within them in the first palce. God must first give the person the gift of the truth, then they will recognize it when they hear it.
