"On that day people will regard their Maker, and their eyes will look to the Holy One of Israel; they will not have regard for the altars, the work of their hands, and they will not look to what their own fingers have made, either the sacred poles or the altars of incense."
There's big business in religion. People and organizations spend BILLIONS every year on religious "things" - books, icons, jewelry, music, clothing, etc. Churches & faith communities invest tons of money in buildings and edifices, equipment & instruments - all for the sake of their faith (whatever faith that may be!).
Isaiah 17 speaks of a time when all the "religious stuff" that people focus on will be of no real importance. What WILL be important is that they come to seek the LORD. Directly. Now, I recognize the original context of this passage was addressed to those nations who worshiped other gods. And yet, this is a message that we in the Christian faith need to take seriously, too! No matter how many Christian t-shirts, crosses, CDs or Bible translations we may have... no matter how beautiful our churches may be... what really matters is that we seek God. Period. And, the Bible assures us (and I can attest to this fact!) that God will be found. Amen to that!
