God is Omniscient.

"He knew all men" (John 2:24). "You, Lord, . . . know the hearts of all men" (Acts 1:24). "And Jesus knowing their thoughts said, 'Why are you thinking evil in your hearts?'" (Matthew 9:4).

One way that we can see that God knows all things is by seeing in the New Testament that Jesus (God in the flesh) knows all things. He knows all things that will come to pass. "Jesus, [knew] all the things that were coming upon Him" (John 18:4). On the basis of this knowledge, he foretold numerous things that his friends and enemies would do. "[Jesus said] 'There are some of you who do not believe.' For Jesus knew from the beginning who they were who did not believe, and who it was that would betray Him" (John 6:64). "From now on," he said, "I am telling you before it comes to pass, so that when it does occur, you may believe that I am" (John 13:19).

John Piper writes,

The greatest thing that can be said of Jesus' knowledge is that he knows God perfectly. We know God partially and imperfectly. Jesus knows him like no other being knows him. He knows him the way an omniscient Person knows himself. "All things have been handed over to Me by My Father; and no one knows the Son except the Father; nor does anyone know the Father except the Son, and anyone to whom the Son wills to reveal Him" (Matthew 11:27). No one but Jesus knows the Father immediately, completely and perfectly. Our knowledge of the Father depends wholly on Jesus' gracious revelation; it is derivative and partial and imperfect.Nothing greater can be said about the knowledge of Jesus than that he knows God perfectly.

God is amazing. The Triune God knows all things past, present, and future. He doesn't just know events but he knows people. He knows things about you and me that we do not know and may never know.

Nothing can be concealed from God.

Nothing escapes his notice, nothing can be hidden from him, nothing is forgotten by him....His knowledge is perfect. He never errs, never changes, never overlooks anything. A.W. Pink

Here are some more passages of Scripture that talk about God's knowledge:

Hebrews 4:13 "And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account."

Ezekiel 11:5 "For I know the things that come into your mind"

Psalm 90:8 "You have set our iniquities before you,
our secret sins in the light of your presence."

How Great and worthy of worship and honor our God is. Our knowledge of God's omniscience should fill us with amazement, awe, and adoration. "The eyes of the Lord are in every place, keeping watch on the evil and the good."

This week think about what this means for our lives. What are the implications for your life?
