God Knows Everything

A devotional by Grace To You for reading on February 15th

“Great is our Lord, and abundant in strength; His understanding is infinite” ( Psalms 147:5 5 Great is our Lord, and mighty in power; His understanding is infinite. ).

God knows everything, and so He knows our sin.

Our time in history has been called “the Information Age.” Computers work around the clock storing the glut of information from all branches of knowledge. And this flood of data is growing bigger all the time. Without the help of advanced technology, we could process and interpret only a tiny fraction of it.

In contrast, God is omniscient; He knows everything. Our Scripture for today says, “His understanding is infinite.” Isaiah asks, “Who has directed the Spirit of the Lord, or as His counselor has informed Him? With whom did He consult and who gave Him understanding? And who taught Him in the path of justice and taught Him knowledge, and informed Him of the way of understanding?” (40:13-14). The answer to all those questions is, “No one.”

Since His knowledge is infinite, God never learns anything, nor does He forget anything. When you pray, you’re not telling God something He doesn’t know. He merely chooses to work through our prayers.

God knows every detail of our lives. Jesus says, “The very hairs of your head are all numbered” ( Luke 12:7 7 But the very hairs of your head are all numbered. Fear not: ye are of more value than many sparrows. ). God doesn’t have to count them because He intrinsically knows how many there are. He also knows all our thoughts (Isa. 66:18). David says, “Even before there is a word on my tongue, behold, O Lord, Thou dost know it all” (Ps. 139:4). In that same psalm, David goes on to say, “Even the darkness is not dark to Thee” (v. 12). You can’t hide anything from the knowledge of God.

God’s omniscience should be a deterrent to our sinning. Think about some of the wrongs you did as a child when your parents weren’t around. You never would have done those things in front of them because you didn’t want to be punished. And you might have gotten away with a few things. But “God will bring every act to judgment, everything which is hidden, whether it is good or evil” (Eccles. 12:14). Even though the eternal penalty for sin has been paid by Christ, God still disciplines us when we sin (Heb. 12:5-11). Is there anything in your life you would be ashamed about if God knew? If so, repent, because He does know!

Suggestions for Prayer

Praise God for His infinite knowledge.

For Further Study

Read David’s praise for God’s omniscience in Psalms 139:1-6 Chapter 139 1 O Jehovah, thou hast searched me, and known `me'. 2 Thou knowest my downsitting and mine uprising; Thou understandest my thought afar off. 3 Thou searchest out my path and my lying down, And art acquainted with all my ways. 4 For there is not a word in my tongue, But, lo, O Jehovah, thou knowest it altogether. 5 Thou hast beset me behind and before, And laid thy hand upon me. 6 `Such' knowledge is too wonderful for me; It is high, I cannot attain unto it. . What specific areas of God’s knowledge does he mention?
