"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; Hebrews 8:11)
We will "know the Truth, and the Truth will make you free.” (John 8:32)
That is GOOD NEWS!
