Now, little children, remain in him, that when he appears, we may have boldness, and not be ashamed before him at his coming.
I believe that John is here referring to spiritual development.There are people who have just received the Lord and they are babes in Christ. "I write unto little children," little children in your experience, and what he has to say to them is that your sins are forgiven. And hey, that's great, that's where you start. And there are a lot of people who are new in the Lord, and about the only thing they know is that their sins are forgiven. You know, they are not really versed in Christian doctrine. They really don't know too much yet about the nature of God and the nature of man and the nature of angels. They don't know much of Christian yet, but at least they know the important thing, that their sins are forgiven. And how important it is that we know that fact, that our sins are forgiven. So that's sort of your infancy state. In your first realization as a child of God is the fact that my sins are forgiven.
