In this sermon, Pastor Sam Kraemer explores Psalm 139 and delves into the difference between head knowledge and heart knowledge. He highlights the three omni characteristics of God - omniscience, omnipresence, and omnipotence - and emphasizes the personal knowledge that God has of each individual. Pastor Sam discusses how God knows everything about us, is always with us, and intimately formed us. He concludes with a call to know God in return and invites listeners to examine their hearts and seek the way everlasting.
