But again, I would say that is not the focus when the indwelling Holy Ghost would lead every believer to see to continue their reconciled relationship with God thru Jesus Christ.
How can you avoid people that make false claims about the Holy Ghost then if one looks for such people?
1 Corinthians 3:5 Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? 6 I have planted, Apollos watered; but God gave the increase. 7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase....….21 Therefore let no man glory in men. For all things are your's; 22 Whether Paul, or Apollos, or Cephas, or the world, or life, or death, or things present, or things to come; all are your's; 23 And ye are Christ's; and Christ is God's.
1 Corinthians 1:29 That no flesh should glory in his presence. 30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 31 That, according as it is written, He that glorieth, let him glory in the Lord.
It is His workmanship in us and others that will be glorified.
2 Corinthians 3:1Do we begin again to commend ourselves? or need we, as some others, epistles of commendation to you, or letters of commendation from you? 2 Ye are our epistle written in our hearts, known and read of all men: 3 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.4 And such trust have we through Christ to God-ward: 5 Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God; 6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
2 Corinthians 4:5 For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake. 6 For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. 7 But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.
Romans 12:1I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. 2 And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God. 3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith. 4 For as we have many members in one body, and all members have not the same office: 5 So we, being many, are one body in Christ, and every one members one of another.
1 Corinthians 1:9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord. 10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
1 Corinthians 2:2 For I determined not to know any thing among you, save Jesus Christ, and him crucified.
Only you can know the Holy Spirit is in you.
John 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
By His words towards professing believers is how we know He is in them.
John 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Galatians 3:14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith....26 For ye are all the children of God by faith in Christ Jesus.
Hebrews 11:1Now faith is the substance of things hoped for, the evidence of things not seen. 2 For by it the elders obtained a good report.
He is even in former believers still.
2 Timothy 2:11 It is a faithful saying: For if we be dead with him, we shall also live with him: 12 If we suffer, we shall also reign with him: if we deny him, he also will deny us: 13 If we believe not, yet he abideth faithful: he cannot deny himself.
