Isa 55:6  Seek the LORD while he may be found, call upon him while he is near: 

There is a time that is called “while He may be found.” It is a mysterious thing, perhaps, “while it is yet day.” No matter, there is no doubt there is a time to seek the Lord while He may yet be found. In the broadest sense and for the most part it is life itself. Almost always while there is yet breath in our lungs, He may be found. Yet in the the very next sentence we are told “let the wicked forsake his way (note the singular nature of the word, it does not say his ways) The wicked are on a wrong path altogether and in order to turn to God they must reverse their course and go in the exact opposite direction. Yet it’s not just his way that has to change, it’s his thoughts too. It is not so much what we are saved out of, for the Lord can deliver us from the gates of hell, it is what we are saved into. The thoughts of a man make up the core of who he is. The true measure of the new man in the new birth is that his very mind has been transformed. And from the depths of who he is, God changes him from the inside out. And now we shall see, glory to God, that out of the abundance of a mans heart the mouth speaks. And it speaks of Jesus.

Now it is certainly true that God will not always strive with a man. A mans heart can be so hardened and his conscience so seared that his time has come and gone, this is a truly terrifying position. If you find yourself coming close to that place, turn and run to God with everything that is in you. He shall still be found. For He will have mercy upon that man and He will abundantly pardon. We as saints may be tempted to think we are living in a world that is beyond redemption, I have thought that thought many times. Yet here is the humility, God says, My thoughts are not your thoughts nor are your ways My ways. For as the heavens are higher than the earth so are My ways higher than your ways and My thoughts than your thoughts.(Isa 55:8-9) And so just as the rain and the snow falls from the heavens and waters the earth and it brings forth seed for the sower and therefore bread for the hungry, so also does the Word of the God fall down upon the earth. It comes forth from His heart and it always accomplishes what He desires. To the thirsty, behold, water. To the hungry, behold, bread.

And so to those who are watered by the Lord, those who have sought Him out, their thirst is quenched to overflowing. And to those who have been fed by the Lord, they are filled to abundance. They shall stretch out the curtains of their spiritual dwellings for it shall be enlarged. They shall go forth with joy and be led out by peace and the mountains and the hills shall burst into singing before them. And the trees of the field shall clap their hands in delight to see such things. It can clearly be seen that goodness and mercy are following them all the days of their lives. And the thorns and the cares of life are replaced by fruitful trees and evergreens. And they shall always bring forth His fruit in season and they shall never wither for they are as the ones planted by the river, the river of God, the river of life and this river runs with them wherever they go.
