The Hebrew yada' has a wide range of applications, but its basic meaning is "to know." In Genesis 4:1, 17, 25 it is translated "knew" and describes the sexual part of the husband-wife relationship, which suggests the deepest intimacy of heart and mind. This matters for John 17:3, where Jesus defines eternal life as knowing the only true God and Jesus Christ. The corresponding Greek word, ginosko, can be used the same way as yada' (see Luke 1:34). Knowing God therefore means more than intellectual acquaintance. It means an intimate, personal relationship, as if being "inside His head," and it includes mental, emotional, and experiential knowledge. The fruit of this intimacy is love, reverence, obedience, honor, gratitude, and deep affection. Through it we come to know God as Ruler, Master, parent, brother, friend, Savior, and Lawgiver, and these qualities compel wholehearted yielding to Him. This knowledge has practical power. Hosea 4:6 shows that lack of knowledge of God brings destruction, while Proverbs 3 shows that knowledge enriches the quality of life. Eternal life is thus not merely endless existence but life of God's own quality, lived in fellowship with Him and in imitation of His giving way of life.

The Hebrew yada, translated "know," has a wide range of application, and one of its uses is sexual intimacy, as in Genesis 4:1, 17, and 25, where Adam and Cain "knew" their wives and conceived. This adds closeness to the idea of knowing, so that knowledge is more than detached acquaintance. The Greek ginosko carries the same sense, as in Luke 1:34, where Mary says she does not "know" a man. It is the same word translated "know" in John 17:3, so Hebrew, Greek, and English use the term the same way. When Jesus defines eternal life as knowing the only true God and Jesus Christ, He means an intimate relationship, not mere information about God. This is knowledge acted upon: it includes love, reverence, obedience, honor, gratitude, and deep affection, and it recognizes God as Sovereign, parent, friend, and lawgiver, and Christ as Elder Brother and husband-to-be. Such knowledge is power. Hosea 4:6 shows that people perish for lack of it, and Isaiah 11:9 shows that the earth will be full of the knowledge of the LORD, which gives the Millennium its quality of life. Knowing God is shown by keeping His commandments (I John 2:3-6), and it produces a life lived the way God lives, a life of giving.

Yada, the most frequent Hebrew word for "know," goes far beyond awareness of facts. In Psalm 1:6 the LORD "knows" the way of the righteous, meaning He takes delight in them and blesses them. In Genesis 4:1, "Adam knew Eve," the word carries closeness, devotion, cherishing, and eager understanding of specific things about someone with whom one has a personal relationship. This realistic sense of knowing is experiential rather than detached or academic. Knowing a plague of the heart, the loss of children, or grief means suffering it personally, as Christ did when He became acquainted with grief. Because the Bible sees the whole person as involved, knowing God engages facts, practical experience, and a delighted emotional response, not the mind alone. Knowledge of God shows itself in conduct that fits the relationship. Israel had book knowledge but did not know God, since they failed to act as His children, while Josiah knew God because he did justice as God would have done it. John 17:3 therefore makes knowing God synonymous with eternal life, and 1 John 2:3-6 shows that one knows God by keeping His commandments, His broad instruction. To know God is to live like God, and God knows us by our actions just as we come to know Him by doing His will. Jesus' declaration "I never knew you" falls on those who do not obey.

To know God, yada in Hebrew and ginosko in Greek, is the factor that undergirds living faith and enables good works. Eternal life is to know God. Daniel 11:32 says, "the people that do know their God shall be strong, and do exploits." This knowing combines close, warm, even passionate intimacy with head knowledge. It gives a person an edge that lets him trust God and at the same time perceive what God is doing. It is no casual acquaintance but the foundation of a true working relationship, and it is what gives God's Word authority in our hearts. Knowing God means believing that He is holy, so His anger burns against sin; righteous, so His judgments fall on the rebellious; faithful, so His promises of blessing or cursing are absolute; omnipotent, so no one can resist Him; and omniscient, so no problem escapes Him or defeats Him. Moses is the example. He forsook Egypt, not fearing the king's wrath, because he endured as seeing Him who is invisible. Because he knew God, he was strong and did great exploits. Those who know God's character, that He is too wise to err and too loving to let them be overwhelmed, can endure the mysteries and disappointments of life. They trust that Romans 8:28 still stands and live with a peace that passes all understanding.

In Hosea 4:6, the word for knowledge comes from the root yada, which is rooted in the idea of intimacy. God's people are those who hold His revealed and hidden knowledge, yet they are destroyed for lack of that intimacy with Him, not for lack of information. Amos 3:2 confirms this: "You only have I known" (yada) of all the families of the earth. God knows every nation and every star, so this knowing means an intimate relationship in which He revealed hidden secrets to Israel, and therefore He punishes their iniquities. The surrounding words complete the picture. "Lack" means a gradual wearing down or withdrawal, and "reject" means to melt away, like a candle burning down to a blob of wax until the fire goes out. The problem is not a sudden rejection of intimacy with God but a slow melting of it through lawlessness, much like a marriage that falls apart when affection fades. The result is that Israel was divorced, lost its priestly calling, and was sent into captivity. The same applies to spiritual Israel. Leaving one's first love (Revelation 2:4) and letting love grow cold because of lawlessness (Matthew 24:12) forfeits a place as priests in God's Kingdom. Intimate knowledge of God is kept by obeying His commandments and by growing in the qualities of II Peter 1, so that one never lacks in the knowledge of Christ.

In the context of understanding God's sovereignty, the Hebrew word yada (H3045), meaning "to know," carries profound significance. As seen in Daniel 11:32, "the people who know their God shall be strong, and carry out great exploits," yada indicates a close, warm, and even passionate intimacy combined with intellectual understanding. This deep relationship provides an edge in a person's life, enabling trust in God and the perception of His actions. It forms the very foundation of a true, working willingness to submit to His sovereignty. Through this intimate knowledge, believers recognize God's holiness, righteousness, faithfulness, omnipotence, and omniscience, understanding that His anger burns against sin, His judgments fall on rebels, His promises are absolute, no one can resist Him, and no problem is beyond His mastery. This knowing empowers faith to endure life's disappointments and mysteries, assuring believers that the sovereign God is involved in their lives and too wise and loving to allow them to be overwhelmed.

In Daniel 11:32, it is written that the people who know their God shall be strong and carry out great exploits. This concept of knowing God is deeply explored through the Hebrew word yada' (H3045), which signifies an intimate, experiential understanding. In Amos 3:2, God declares to Israel, "You only have I known of all the families of the earth," using yada' to express a unique, close relationship, implying that those He knows intimately are subject to His correction and punishment for their iniquities. The term yada' conveys a profound connection, often illustrated by the imagery of a husband and wife. In Hosea 2:19-20, God says, "I will betroth you to Me forever... and you shall know the Lord," using yada' to indicate an intimate experience with Him. Similarly, in Jeremiah 9:23-24, God invites glory in understanding and knowing Him through yada', revealing His character as one of lovingkindness, judgment, and righteousness, traits in which He delights. This intimate knowing is not merely intellectual but requires obedience and love. As seen in I John 2:3-6, we know that we know Him if we keep His commandments, and whoever keeps His word has the love of God perfected in them. Conversely, Jesus warns in Matthew 7:21-23 and other passages that many who claim to know Him will hear, "I never knew you; depart from Me, you who practice lawlessness," indicating a lack of true intimacy with Him despite their claims. Thus, to know God through yada' is to live in alignment with His will, reflecting His character in our actions and relationships.

In Exodus, the phrase that God acknowledged the children of Israel means that He knew them. This knowing refers to taking note of them with a view to caring for them. He knew them with a view toward loving them and took an intense interest in them. This act initiated their deliverance from bondage. The same knowing appears in the statement that God chose Israel because He loved them. This knowing shows God as the initiator who notices individuals with a view to caring for them and bringing them into freedom.

The Hebrew word yada' (H3045), translated as "to know" or "to decide" in Genesis 3:22, is a primitive root meaning to ascertain by seeing. In the original Hebrew, it is represented as a pictograph of a door and an eye, symbolizing the concept of "the door of the eye." This indicates that the eye serves as the window into a person's very being, where experience is gained through visual observation, and knowledge is achieved through these experiences. However, decisions based on anything other than the truth of God's Word will never create a solid foundation for what is built upon them. Since the moment Adam and Eve took from the Tree of the Knowledge of Good and Evil, humanity has been under the seduction to decide for themselves what is good and evil, leading to foundations cursed with cracks apart from the truth found in Jesus Christ.
