Psalm 100:3a
3a Know ye that the LORD he is God: it is he that hath made us, and not we ourselves.
Biblical religion is knowledge-based; it is based, in particular, on the knowledge of the living and true God. True worship never occurs without the knowledge that the LORD is God. False ideas of God lead to idolatry and superstitions. Hence, the admonition to all is: “Know ye that the LORD he is God”. The name “the LORD” in Hebrew is “Yehowah”, which is transliterated into English as Jehovah. This name of God appears 6,518 times in the Hebrew Old Testament Scriptures. In the King James Bible, “Yehowah” is translated as “LORD” 6,510 times, “GOD” four times, and “JEHOVAH” four times. It has never been used to refer to any other god or person in the Bible. The LORD is God in the fullest, most absolute and most exclusive sense.
“Yehowah” denotes the self-existence of God (cf. Exodus 3:13-15). The LORD is the eternal God. He is without beginning and end. He is also our Creator. It is the LORD who “hath made us, and not we ourselves”. Hence, we must know that there is no God besides the LORD. Unto Israel, it was declared through Moses, “Unto thee it was shewed, that thou mightest know that the LORD he is God; there is none else beside him … Know therefore this day, and consider it in thine heart, that the LORD he is God in heaven above, and upon the earth beneath: there is none else” (Deuteronomy 4:35, 39). Likewise, the prophet Jeremiah declared, “But the LORD is the true God, he is the living God, and an everlasting king” (Jeremiah 10:10). It is repeatedly asserted that the LORD of Israel (who has revealed Himself in the Scriptures) alone is God (cf. Joshua 22:30; 1 Kings 8:60; 18:39; 2 Kings 19:19; Isaiah 44:6, 8, 24; 45:5-6, 22; Hosea 13:4; Joel 2:27; John 17:3; Acts 17:23-24).
Every worshipper must acknowledge and confess that the LORD alone is God. Even more, they must seek to know Him more and more with great wonder, thankfulness and reverence. God’s people have been instructed: “Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations” (Deuteronomy 7:9). Through the prophet Hosea, the LORD also said that He desired “the knowledge of God more than burnt offerings” (Hosea 6:6). We must know the LORD and prove our knowledge of Him by our faith, obedience, zeal and love towards Him.
