But it is to the extent of your hardness and unrepentant heart

"But because you are stubborn and your heart does not repent" or "But because you are stubborn and refuse to repent"

you are storing up for yourself wrath

The longer they go without repenting, the more severely God will punish them. Alternate translation: "you are making your punishment worse"

on the day of wrath ... the day of the revelation of God's righteous judgment

Both of these phrases refer to the same day. Alternate translation: "when God will show everyone that he is angry and that he judges all people fairly"
