"I will stop all her celebrations: her yearly festivals, her New Moons, her Sabbath days - all her appointed feasts." NIV translation
All of the woman's (Israel's religious events) will be stopped. God is a jealous God and does not want them (or us) to follow Him only with religious acts. God's desire is for our hearts to be like that of Jesus.
"I will ruin her vines and her fig trees, which she said were her pay from her lovers; I will make them a thicket, and wild animals will devour them." NIV translation
Because of the adultery of the woman ( & Israel), God will remove his provision of food. They did not acknowledge that it was from God so He will no longer provide it.
"'I will punish her for the days she burned incense to the Baals; she decked herself with rings and jewelry, and went after her lovers, but me she forgot, declares the Lord.'" NIV translation
Now, we see the how God compares the physical adultery of a woman with the spiritual adultery of turning to Baals. Baal means "my lord" and in Hebrew it means master and we see that the woman (Israel) turned to call someone else master rather than the God of the universe who created her.
"'Therefore I am now going to allure her; I will lead her into the desert and speak tenderly to her. There I will give her back her vineyards, and will make the Valley of Achor a door of hope. There she will sing as in the days of her youth, as in the day she came up out of Egypt.'" NIV translation
Even after turning their backs on God, He says that He will draw them back to Himself. Achor means trouble and He says that He will turn their troubles into hope. That is what He does for us through the precious blood of Jesus Christ.
"'In that day,' declares the Lord, 'you will call me "my husband"; you will no longer call me "my master."'" NIV translation
God tells the woman (Israel) that, when she turns back to Him, it is no longer as a slave. A husband loves and gives all he has for his wife where a master only uses a slave for their own purposes. In the world today, the idea of being married does not mean as much as it should. But, here, God is assuring them and us that it is forever.
