Summary: The first in a series on the Character of God from Psalm 139. The Omniscience of God.

The Character of God—Part 1—God Knows

Psalm 139:1-4 O LORD, you have searched me and you know me. 2 You know when I sit and when I rise; you perceive my thoughts from afar. 3 You discern my going out and my lying down; you are familiar with all my ways. 4 Before a word is on my tongue you know it completely, O LORD.

I. God knows and understands you.

A. It is not self-knowledge, but God’s complete knowledge that is chiefly important for us.

1 Corinthians 8:2,3 The man who thinks he knows something does not yet know as he ought to know. 3 But the man who loves God is known by God.

Our aim is not necessarily to understand and know more about ourselves, but to be known and understood by God—and to base our knowledge and understanding of ourselves on that—on God’s assessment of us—not on our assessment of ourselves.

B. God knows our hidden strengths and abilities. This is why God was able to choose many people to do incredible things for him that wouldn’t have been our top candidates. Gideon.

C. God knows our human frailties—he knows our weaknesses.

Psalm 103:13,14 As a father has compassion on his children, so the LORD has compassion on those who fear him; 14 for he knows how we are formed, he remembers that we are dust.

D. God knows how to protect and care for you. Jesus reveals that his knowledge of us allows him to be a good shepherd—caretaker—for us. When a shepherd knows the weakness of his sheep, he can protect against that weakness.

John 10:14 "I am the good shepherd; I know my sheep and my sheep know me--

II. God knows everything that happens.

A. Nothing is hidden from God—all is known by him.

Daniel 2:22 He reveals deep and hidden things; he knows what lies in darkness, and light dwells with him.

B. God knows both the good and the bad.

To Philadelphia, Jesus said of their good deeds:Rev. 3:8a “I know your deeds.”

Revelation 3:14,15a "To the angel of the church in Laodicea write: These are the words of the Amen, the faithful and true witness, the ruler of God’s creation. 15a I know your deeds,

C. Because God knows the deeds and the heart, he is able to judge completely and fairly. He knows not only what we say and do—but even what is going through our minds—the intents of the heart.

Luke 16:15 He said to them, "You are the ones who justify yourselves in the eyes of men, but God knows your hearts. What is highly valued among men is detestable in God’s sight.

III. God knows even the future.

A. God’s complete knowledge of the future is clear throughout Scripture. We are told to rely on this knowledge.

B. We, in contrast, do not know the future. Therefore, all that I know about the future is only in accordance with what has been revealed by God.

Ecclesiastes 8:7 Since no man knows the future, who can tell him what is to come?

C. This calls for us to submit to God for the future.

James 4:14 Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. 15 Instead, you ought to say, "If it is the Lord’s will, we will live and do this or that."

IV. God’s knowledge is perfected—in that God doesn’t just know intellectually. He knows experientially.

A. There is a benefit to experiential knowledge over intellectual knowledge.

JOB 42:5 My ears had heard of you but now my eyes have seen you.

B. Jesus came down and experienced life as a human—so that he knows—he knows everything about us—in a sense that goes beyond his spiritual complete knowledge—so that his complete knowledge is perfected.

C. It is revealed that it is this experiential knowledge that allows Jesus Christ to justify us.

Isaiah 53:11 After the suffering of his soul, he will see the light of life and be satisfied; by his knowledge my righteous servant will justify many, and he will bear their iniquities.


Psalm 139:23,24 Search me, O God, and know my heart; test me and know my anxious thoughts. 4 See if there is any offensive way in me, and lead me in the way everlasting.

A. Because of his complete knowledge, God and only God is qualified to search through our hearts—this invitation for him to search your heart is a recognition of and submission to his omniscience—which allows you to receive the following benefits.

B. From the understanding and perspective of God’s complete knowledge we are able to have peace—even in situations which would induce anxiety. Our anxieties are quieted when we realize God’s knowledge:
