"Seek the LORD while he may be found ..." Is 55:6 (ESV)

In Isaiah 55 God calls to the needy, offers supplies and asks us why we keep ourselves busy with useless and worthless things.

Come, everyone who thirsts,
come to the waters;
and he who has no money,
come, buy and eat!
Come, buy wine and milk
without money and without price.
Why do you spend your money for that which is not bread,
and your labor for that which does not satisfy?
Listen diligently to me, and eat what is good,
and delight yourselves in rich food.
Incline your ear, and come to me ... Isaiah 55:1-3 (ESV)

God calls out with what we need and wonders why we get caught up in aimlessness. After all, he made us and designed our world, why wouldn't he know what's best? This same call for support is offered as an "everlasting covenant" (Is 55:3 ESV) to those of us who are unresisting enough to enjoy what he has to offer.

Offering to help a people cast aside, God says:
Seek the Lord while he may be found; call upon him while he is near; ... let the wicked forsake his way ...let him return to the LORD, that he may have compassion on him, and to our God, for he will abundantly pardon.

For my thoughts are not your thoughts,
neither are your ways my ways, declares the LORD.
Isaiah 55:6-8 (ESV)

I've usually heard Is 55:8 used to say: Don't do things your way, you're only human and God knows best.
Though that is a true idea, I think that in this chapter God is saying: Anyone can come back. Anyone can get what I'm offering.

Kind of makes me think of Luke 15.
