Your theology determines your behavior.
Contrary to the popular tenet of many—that it does not matter what you believe, the Scriptures emphatically contradict this lie of Satan. What you believe about God (i.e. your theology) determines your behavior. Psalm 94 clearly demonstrates this with the following description of first the behavior and then the theology of the wicked: “They utter speech and speak insolent things; all the workers of iniquity boast in themselves. They break in pieces Your people, O Lord, and afflict Your heritage. They slay the widow and the stranger and murder the fatherless. Yet they say, ‘The Lord does not see, nor does the God of Jacob understand’” (vv. 4-7).
When you believe that God is not omniscient (i.e. He does not see) and He is amoral (i.e. He is neither a rewarder of those who seek Him nor a punisher of those who disobey Him), your theology will produce wicked behavior. When modern-day supporters of abortion declare that murdering the innocent is the work of God, there is a fundamental, fatal flaw in their theology. When proponents of sexual perversion of any kind contend that there is divine approval of such a lifestyle, there is a fundamental, fatal flaw in their theology.
To believe that “The Lord does not see nor…understand” is to believe the absurdity that the creature is greater than the Creator. What folly! “He who planted the ear, shall He not hear? He who formed the eye, shall He not see? He who instructs the nations, shall He not correct, He who teaches man knowledge?” (vv. 9-10). The Lord knows the foolish thoughts of the wicked (v. 11). What fatal folly it is to think and believe otherwise.
“Blessed is the man whom You instruct, O Lord, and teach out of Your law” (Psalm 94:12).
Blessed is the man who rejects the fundamental, fatal flaw of the wicked.
