Hear, O Israel: The LORD our God, the LORD is One.
Significance
"Knowing" God not merely cognitive—means living in fellowship (cf. Hebrew "know" encompassing sexual intimacy, Genesis 4:1 LXX). Though God can be known through creation (Romans 1:18-25), ultimately knowledge contingent upon salvation (Barrett; Wisdom 15:3). Dead Sea Scrolls: "life"/"eternal life" and "eternal knowledge" in close parallelism. God = "only true God" affirmed supremely in Shema (Deuteronomy 6:4). Jesus = exclusive agent, sole authorized representative; God-sent Messiah.
