Built altars for sin offerings becomes altars for sinning

Hosea 8:8-14
Though Ephraim built may altars for sin offerings, these have become altars for sinning.
I wrote for them the many things of my law, but they regarded them as something alien.
They offer sacrifices given to me and they eat the meat, but the Lord is not pleased with them.
Israel has forgotten his Maker and built palaces; Judah has fortified many towns. But I will send fire upon their cities.
Neither idols not allies will avail(可用) when the God they have forgotten strikes(打擊)
Why?
They did sacrifices for the Lord but God is not pleased with them for they did the ceremony only forgot obey the law God gave them.
Secular is overwhelmed in this world, if there is not the word of God people will  turn to corruption.
Every holy things be done with evil heart will become to sins and destroy.
Remember the grace and mercy of the Lord did upon me!
How?
What should I obey the word of God? Pray the Lord give me a pure heart!
