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

but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him

I write unto you, my little children, because your sins are forgiven you for his name’s sake. I write unto you, fathers, because ye know him who is from the beginning. I write unto you, young men, because ye have overcome the evil one. I have written unto you, little children, because ye know the Father. I have written unto you, fathers, because ye know him who 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 evil one.

And ye have an anointing from the Holy One, and ye know all things.

As for you, let that abide in you which ye heard from the beginning. If that which ye heard from the beginning abide in you, ye also shall abide in the Son, and in the Father.
