Symbolically, adultery is used to express unfaithfulness to God, and we can easily see this in Israel's idolatry. God is represented as the husband of His people. Ezekiel 16:15-59 gives a graphic description of Israel's spiritual adultery, and Hosea 1:1-2 shows the same symbolism in Hosea's marriage. We can fall into spiritual adultery by relying on the world and its false teaching rather than God.
