No the Bible does NOT say that a Christian is supernaturally incapable of sinning. That is for when we receive our Glorious incorruptible Bodies. That time has most certainly not come yet for ANY Christian.
Yes, Christians are to strive to avoid sin with all they have, but that is not the same as saying a Christian CANNOT sin. Regardless of whether they believe, or are saved by Christ's blood, or not. '
It makes no difference. Christians are CAPABLE of sinning and offending the Holy Spirit in their stumbling.
That is what James 3:2 is talking about.
Yup, I am in full agreement with you here yet we have many "sinless ones" on this platform.
As you rightly said, we have not reached our final redemption, the redemption of our bodies.
Heb 12:3 For consider him that hath endured such gainsaying of sinners against themselves, that ye wax not weary, fainting in your souls.
Heb 12:4 Ye have not yet resisted unto blood, striving against sin:
Heb 12:5 and ye have forgotten the exhortation, which reasoneth with you as with sons, My son, regard not lightly the chastening of the Lord, Nor faint when thou art reproved of him;
Heb 12:6 For whom the Lord loveth he chasteneth, And scourgeth every son whom he receiveth.
Heb 12:7 It is for chastening that ye endure; God dealeth with you as with sons; for what son is there whom his father chasteneth not?
Heb 12:8 But if ye are without chastening, whereof all have been made partakers, then are ye bastards, and not sons.
Heb 12:9 Furthermore, we had the fathers of our flesh to chasten us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
Heb 12:10 For they verily for a few days chastened us as seemed good to them; but he for our profit, that we may be partakers of his holiness.
Heb 12:11 All chastening seemeth for the present to be not joyous, but grievous: yet afterward it yieldeth peaceable fruit unto them that have been exercised thereby, even the fruit of righteousness.
Heb 12:12 Wherefore lift up the hands that hang down, and the palsied knees;
Heb 12:13 and make straight paths for your feet, that that which is lame be not turned out of the way, but rather be healed.
Heb 12:14 Follow after peace with all men, and the sanctification without which no man shall see the Lord:
Heb 12:15 looking carefully lest there be any man that falleth short of the grace of God; lest any root of bitterness springing up trouble you, and thereby the many be defiled;
Heb 12:16 lest there be any fornicator, or profane person, as Esau, who for one mess of meat sold his own birthright.
Heb 12:17 For ye know that even when he afterward desired to inherit the blessing, he was rejected (for he found no place of repentance), though he sought it diligently with tears.
