Knowing Him

It will happen progressively.

“No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know Me, from the least of them to the greatest.” (Hebrews 8:11)

You will know Him when He ‘forgives your sins’ (applies to all) as this verse elaborates the details:

“No longer will they teach their neighbor, or say to one another, ‘Know the LORD,’ because they will all know Me, from the least of them to the greatest,” declares the LORD. “For I will forgive their wickedness and will remember their sins no more.” (Jeremiah 31:34)

P/S (read carefully):

Evil is done by those who ‘don’t know Him’ (Reason for Evil).

“…If they persecuted Me, they will also persecute you; if they kept My word, they will keep yours also. “But all these things they will do to you for My name’s sake, because they do not know the One who sent Me.” – Lord Jesus Christ (John 15:20 – 21)

“No one who abides in Him sins; no one who sins has seen Him or knows Him.” (1 John 3:6)

and those who don’t know Him “don’t love” in “truth”:

“Whoever does not love does not know God, because God is love.” (1 John 4:8)

Here’s a nice quote regarding Him:

‘As the sun can be seen only by its own light, so Christ can be known only by His own Spirit’ – Robert Leighton
