1 John 2:5, 12-14, 20, 24

But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

I write unto you, little children, because your sins are forgiven you for his name's sake. I write unto you, fathers, because ye have known him that is from the beginning. I write unto you, young men, because ye have overcome the wicked one. I write unto you, little children, because ye have known the Father. I have written unto you, fathers, because ye have known him that is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one.

But ye have an unction from the Holy One, and ye know all things.

Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father.
