Isaiah 57:11

"And of whom hast thou been afraid and in fear, that thou liest, and hast not remembered me, nor laid it to heart? have not I held my peace even of long time, and thou fearest not. I will declare thy righteousness; and as for thy works, they shall not profit thee. When thou criest, let them that thou hast gathered deliver thee; but the wind shall take them, a breath shall carry them all away: but he that taketh refuge in me shall possess the land, and shall inherit my holy mountain."

"Israel's original possession of the land was unconditional. It was given to them in fulfillment of the promise to Abraham (Genesis 12:7); and it was intended to be theirs permanently, `forever' (Exodus 32:13); but the retaining of the land was conditional (Leviticus 26:14,15)." It would appear, then, that at the time God gave these prophecies through Isaiah, there was, even that late, a possibility that Israel might repent, turn away from idols, and return to the true worship of God. Their failure to do so resulted in the captivity. These verses are an exhortation to Israel to repent, coupled with the warning that the false gods in which they trust will be utterly helpless to aid them.
