What the heck dude, did you actually read the paragraph that you plucked that verse from?
Luke 13:22-30 [NKJV]
And He went through the cities and villages, teaching, and journeying toward Jerusalem. Then one said to Him, "Lord, are there few who are saved?" And He said to them, "Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. "When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, 'Lord, Lord, open for us,' and He will answer and say to you, 'I do not know you, where you are from,' "then you will begin to say, 'We ate and drank in Your presence, and You taught in our streets.' "But He will say, 'I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.' "There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. "They will come from the east and the west, from the north and the south, and sit down in the kingdom of God. "And indeed there are last who will be first, and there are first who will be last."
THESE are the people you are claiming seek God?
The people that GOD HIMSELF announces "I do not know you" and "Depart from Me, all you workers of iniquity."
Why does God say this? ... because they came knocking "once the Master of the house has risen up and shut the door". These people are seeking God when they stand before God at JUDGEMENT, not "while he may be found". [Isaiah 55:6]
How does THAT prove natural ability when God directly says "I never knew you"?
The two options are:
1. They did not seek the true God in life (like Romans 1 - "although they knew God, they did not glorify [Him] as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools, and changed the glory of the incorruptible God into an image" - and Romans 3 - "There is none righteous, no, not one; There is none who understands; There is none who seeks after God." -talk about).
2. Supralapsarianism and Hard Determinism ... they begged God to accept them as they honestly seek him in life and it was GOD that refused to allow them to be saved.
Which of those is the BIBLICAL option?
Folks, notice that Luke 13:24 has been addressed.
