The first epistle of John gives the Christian thirteen indicators (or evidences) that the Holy Spirit is working within the believer:
1. CONFESSION OF PRESENT SINS
If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us. (1 Jn 1:9,10)
2. FORSAKING OF ALL SINS
My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous ( 1 Jn 2:1)
3. KEEPING CHRIST'S COMMANDMENTS
And hereby we do know that we know him, if we keep his commandments. (1 Jn 2:3)
4. REFUSING TO LOVE THE WORLD (SINFUL ATTRACTIONS AND WORLDLINESS)
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. (1 Jn 2:15)
5. ABIDING IN CHRIST (DOING RIGHTEOUSNESS)
And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming.If ye know that he is righteous, ye know that every one that doeth righteousness is born of him. (1 Jn 2:28,29)
6. PURIFYING ONESELF FROM ALL DEFILEMENT
And every man that hath this hope in him purifieth himself, even as he is pure. (1 Jn 3:4)
7. GENUINELY LOVING OTHER CHRISTIANS
For this is the message that ye heard from the beginning, that we should love one another... But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him? (1 Jn 3:11,17)
8. TRYING OR TESTING THE SPIRITS
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. (1 Jn 4:1)
9. BEING WITHOUT TORMENTED FEAR
There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. (1 Jn 4:18)
10. BEING AN OVERCOMER BY FAITH
For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. (1 Jn 5:4)
11. BELIEVING THAT THE HOLY SPIRIT IS WITHIN
He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son. (1 Jn 5:10)
12. HAVING CONFIDENCE IN PRAYER
And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him. (1 Jn 5:14,15)
13. REJECTING ALL IDOLS (REAL AND METAPHORICAL)
Little children, keep yourselves from idols. Amen. (1 Jn 5:21)
