What is meant by the passage "Seek ye the Lord while he may be found"?

        It is a wholesome warning that a probable contingency may arise when the seeker, who postpones his search, may lose his power or disposition to seek. There are many instances of men who have put off seeking until they have made a fortune, or done something else, and then the time they set, having arrived, discover that business habits and long-time associations absorb them. They are out of touch with God. Even in church their thoughts are running on worldly concerns. It is very rare for an old man who has been
indifferent, or careless, or wicked, to turn to God. Not that God is unwilling to be found, but the man has become incapable of seeking him. None who really seek ever fail to find. (Isaiah 55:6)
