Israel had fallen out of sweet fellowship with their God, and God had now turned the flow of blessing and protection off.
What was true for Israel, it true for many Christians today. We have left God, we have committed spiritual adultery against our Savior. We, like the wife of Hosea, have willingly left the one who has provided everything we will ever need. We have caused God to cut off the blessing and protection He promises those who abide in His will.
God is trying to bring us back. He call to us and calls to us, and though we may come back for a season, we always end up leaving again.
How foolish are we to leave everything we could ever want and need, to follow the sin that only satisfies for a season. It is not until we are in it that we realize that that sin that provides this temporary satisfaction is also the sin that does so easily beset us into staying much longer than we would ever want. The only answer is a complete and absolute surrender to God, that will bring full blessing, and cause us to never to have the desire to seek another source of satisfaction.
