Jeremiah 31:33-34

33“But this is the covenant which I will make with the house of Israel after those days,” says the Lord, “I will put My law within them, and I will write it on their hearts; and I will be their God, and they will be My people.

34And each man will no longer teach his neighbor and his brother, saying, ‘Know the Lord,’ for they will all know Me [through personal experience], from the least of them to the greatest,” says the Lord. “For I will forgive their wickedness, and I will no longer remember their sin.”
