Numerous passages of Scripture clearly teach that God is omniscient. The psalmist declared that God “knows the secrets of the heart” (44:21), and that “His understanding is infinite” (147:5). His eyes “are in every place” (Proverbs 15:3). Of Jehovah, the psalmist also wrote:

O Lord, You have searched me and known me. You know my sitting down and my rising up; You understand my thought afar off. You comprehend my path and my lying down, and are acquainted with all my ways. For there is not a word on my tongue, but behold, O Lord, You know it altogether…. Such knowledge is too wonderful for me; it is high, I cannot attain it. Where can I go from Your Spirit? Or where can I flee from Your presence? If I ascend into heaven, You are there; if I make my bed in hell, behold, You are there (139:1-4,6-8).

The New Testament reemphasizes this truth, saying, “God is greater than our heart, and knows all things” (1 John 3:20, emp. added). Not only does He know the past and the present, but the future as well (Acts 15:18; cf. Isaiah 46:10). There is nothing outside of the awareness of God.

If God knows (and sees) everything, some have questioned why certain statements exist in Scripture that seem to indicate otherwise. Why was it that God questioned Cain regarding the whereabouts of his brother Abel if He already knew where he was (Genesis 4:6)? Why did the Lord and two of His angels ask Abraham about the location of his wife if He is omniscient (Genesis 18:9)? And, if God knows all and sees all, why did He say to Abraham concerning Sodom and Gomorrah: “I will go down now and see whether they have done altogether according to the outcry against it that has come to Me; and if not, I will know” (Genesis 18:21, emp. added; cf. Genesis 22:12)? If God is omniscient, why would He need to “go” somewhere to “see whether” a certain people were wicked or not? Does God really know everything?

First, when critics claim that the questions God asked Cain or Sarah (or Satan—cf. Job 1:7; 2:2) suggest that God’s knowledge is limited, they are assuming that all questions are asked solely for the purpose of obtaining information. Common sense should tell us, however, that questions often are asked for other reasons. Are we to assume that God was ignorant of Adam’s whereabouts when He asked him, “Where are you” (Genesis 3:9)? At the beginning of God’s first speech to Job, God asked the patriarch, “Where were you when I laid the foundations of the earth?” (38:4). Are we to believe that God did not know where Job was when He created the world? Certainly not! What father, having seen his son dent a car door, has not asked him, “Who did that?” Obviously, the father did not ask the question to obtain information, but to see if the son would admit to something the father knew all along. On occasion, Jesus used questions for the same purpose. When He questioned the Pharisees’ disciples and the Herodians regarding whose inscription was on a particular coin, it clearly was not because He did not know (Matthew 22:15-22). Likewise, when Jesus asked the multitude that thronged Him, “Who touched Me?” (Luke 8:45), it was not because the woman who touched Him was hidden from Him (Luke 8:47). Jesus knew the woman who was made well by touching His garment, before the woman ever confessed to touching Him (Mark 5:32). Thus, His question was intended to bring attention to her great faith and His great power (Mark 5:34). Truly, in no way are the questions God asks mankind an indication of Him being less than divine.

But what about Jehovah’s statement to Abraham recorded in Genesis 18:21? Did He not know the state of Sodom and Gomorrah prior to His messengers visit (Genesis 18:22; 19:1-29)? Did He have to “learn” whether the inhabitants of these two cities were as evil as some had said? The Bible’s usage of phrases such as “I will know” (18:21) or “now I know” (22:12) in reference to God actually are for the benefit of man. Throughout the Bible, human actions (such as learning) frequently are attributed to God for the purpose of helping us better understand His infinity. When Jehovah “came down to see the city and the tower” built at Babel (Genesis 11:5), it was not for the purpose of gaining knowledge. Anthropomorphic expressions such as these are not meant to suggest that God is not fully aware of everything. Rather, as in the case of Babel, such wording was used to show that He was “officially and judicially taking the situation under direct observation and consideration, it having become so flagrant that there was danger (as in the days of Noah) that the truth of God’s revelation might be completely obliterated if it were allowed to continue” (Morris, 1976, p. 272). Almighty God visited Sodom and Gomorrah likely “for appearance’ sake, that men might know directly that God had actually seen the full situation before He acted in judgment” (p. 342). As Jamieson, Fausset, and Brown noted in their commentary on Genesis: “These cities were to be made ensamples to all future ages of God’s severity, and therefore ample proof given that the judgment was neither rash nor excessive (Ezek 18:23; Jer 18:7)” [1997].

Similar to how God instructs us to pray and make “known” to Him his petitions for his benefit (Philippians 4:6), even though He actually already knows of our prayers and needs before they are voiced (Matthew 6:8), for his profit the all-knowing God sometimes is spoken of in accommodative language as acquiring knowledge.
