Provided the believer remains in faith through Christ, he continues in that anointing and the work of the Holy Spirit within the believer provides sufficiency in the believer's thinking to discern properly.
If the believer is scarred by past thinking, such as placing faith in any other person before Christ, then he falls out of fellowship and the Holy Spirit is not free to further sanctify the believer in sin, but is grieved until the believer returns to God, confesses and turns away from sin, allowing that past sin to be removed as an obstacle to their fellowship.
Which of the 20,000+ Protestant sects has the anointing? (If you say that they all have it, then why do they disagree with each other?)
