Isaiah 66:4, I choose their delusions. When people who know the truth of YHVH apostatise from his truth, in an effort to bring them back to him, he will discipline them as a loving parent to bring his children back to him. This process begins when people allow false gods or heart idols to replace devotion and obedience to YHVH (Ezek 14:1–5).
Many times, people seek YHVH’s blessings and favor, while at the same time worshiping the idols of their hearts. When a person is in this spiritual condition and they ask for YHVH’s guidance in a matter, a person isn’t able to clearly hear the will of YHVH, since any light of truth they may receive from him will be filtered through the tinted windows of their idolatrous hearts. They will hear only what they want to hear from him. In fact, YHVH promises to answer a person “according to the multitude of his idols” because he is “estranged from me by [his] idols” (Ezek 14:5). This is part of the humbling and testing process YHVH puts his people through as they trek through the wilderness of life en route to the Promised Land of their spiritual inheritance. He wants to see what’s in their hearts and determine whether they will obey all of his commandments whole-heartedly or not (Deut 8:2–3).
As a judgment against his wayward people, YHVH will allow them to come under spiritual delusion in an effort to bring them back to him in hopes of helping them to see that the proverbial grass isn’t greener on the other side of the fence.
This is what happened to the prodigal son in Yeshua’s parable when he returned to his father’s house after having lived riotously for a season.
When people turn from YHVH and choose to serve other (or foreign) gods (or idols), YHVH may allow those gods to rise up to enslave his people (Jer 5:19).
Sometimes YHVH will even send a deluding or lying demonic spirit to further deceive his hard-hearted and rebellious people (2 Chr 18:22).
During the end times apostasy, YHVH will send a strong delusion to his saints who don’t love his truth enough to fully obey him. They will end up believing “the big lie” of the man of sin. This man of sin is the agent of Satan and whom Paul characterizes as the lawless or Torahless one (2 Thess 2:8–12).
