The actual definition is : ginṓskō – properly, to know, especially through personal experience (first-hand acquaintance). 1097 /ginṓskō ("experientially know") is used for example in Lk 1:34, "And Mary [a virgin] said to the angel, 'How will this be since I do not know (1097 /ginṓskō = sexual intimacy) a man?'"
This is different then other words that in English translate as know. In Greek there are different meanings that we have made singular into one definition. For instance:
eídō (oida) – properly, to see with physical eyes (cf. Ro 1:11), as it naturally bridges to the metaphorical sense: perceiving ("mentally seeing"). This is akin to the expressions: "I see what You mean"; "I see what you are saying."
-This is used in passages such as Matthew 24:36 "For no one knows the day or the hour."
There are many places in scripture where the experiential 'to know' used. Understanding its true definition radically changes the meaning of these passages. Dwell on the following passages, think about the implications of what they mean with the new revelation of what it means to truly experience God!
"Know the truth and the truth will set you free (John 8:32)."
"Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord (Philippians 3:8)."
"For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known (1 Cor. 13:12)."
-This is beautiful because every 'know' in this passage is an experiential knowing. But the passage points to the future where we will 'know' God completely!
"He was in the world, and the world was made through him, yet the world did not know him (John 1:10)."
This is not an intellectual knowledge!! This is an intimate knowing that only comes through relationship, from first-hand experience! 2 Timothy 3:7 says, 'Always learning and never able to arrive at a knowledge of the truth.' This is what we need to grasp! We need an intimacy that surpasses understanding and is fulfilled in experience. "To have peace that surpasses understanding you need to give up your right to understand (Bill Johnson)." Go after that place, that intimacy with the Lord. Spend time in the quite place and be refreshed through streams of living water. 'For in Him we live and move and have our being.' -Acts 17:28
