Churches have no power.
There is but one church, and every member of that church are redeemed by the righteousness of Christ and not self-righteous.
Matthew 18:14 Even so it is not the will of your Father which is in heaven, that one of these little ones should perish. 15 Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. 16 But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. 17 And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.
1 Corinthians 5:1 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.... 4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, 5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus....... 9 I wrote unto you in an epistle not to company with fornicators: 10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. 11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolator, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. 12 For what have I to do to judge them also that are without? do not ye judge them that are within? 13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.
The idea that you keep yourself righteous is unbiblical.
The Word of God is the Head over each believer and it is to Him we look to in helping us be submissive to the Word of God.
By correcting others according to the scripture is how you wake up the erring brother to be turn to Him for help to be submissive to Him.
Are you indwelt by the Holy Spirit, then your lamp is full.
Our bodies are the temples of the Holy Spirit ( 1 Corinthians 6:19-20 ) and so that seal of adoption is not going anywhere when we grieve the Holy Spirit ( Ephesians 4:30 ), but we can defile out temples by what we build on that foundation and so we need His help to lay aside every weight & sin daily in running that race per Hebrews 12:1-2.
Yet suffering the destruction of the flesh nevertheless. OSAS is true but the warnings given by Jesus are there for the believers for a reason.
Cannot be inference when the church at Thyatira was warned to repent or else be cast into the bed of the coming great tribulation which you acknowledge that warning below and yet....
And? Do you think they did? Who convicted them to repentance?
Jesus, even those who got cast into the bed of the great tribulation when Satan will wage the war on the saints to kill them with death too and not just that fiery calamity that will befall one third of the earth per Revelation 8:7 before the great tribulation comes.
Your understanding of church is lacking.
Scripture supports what I say whereas you are not showing any scripture to support what you say. Don't you usually correct by scripture?
Why would the Spirit stop convicting and leading us all into repentance. What desire is placed into the heart of a believer.
Jesus would not bother to warn of the consequence for saved believers otherwise. Even Paul acknowledge that he could become a castaway too and not just lose the rewards of crowns.
1 Corinthians 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
Do you have special knowledge?
No more than what you can have when you discern with Him at that throne of grace.
1 John 2:20 But ye have an unction from the Holy One, and ye know all things. 21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.... 26 These things have I written unto you concerning them that seduce you. 27 But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. 28 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.
James 1:5 If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. 6 But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.
Hebrews 4:12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. 13 Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do. 14 Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. 15 For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. 16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
2 Timothy 3:13 But evil men and seducers shall wax worse and worse, deceiving, and being deceived. 14 But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them; 15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus. 16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, thoroughly furnished unto all good works.
No harm in asking Him for help in case you are missing something that He wants you to know so you can be pruned and bear more fruit as His disciples so that your joy may be full. There is a risk for not asking Him about this since refusing to be reproved by scripture is a risk.
John 15:1I am the true vine, and my Father is the husbandman. 2 Every branch in me that beareth not fruit he taketh away:
and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. 3 Now ye are clean through the word which I have spoken unto you. 4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5 I am the vine, ye are the branches: He that abideth in me, and I in him,
the same bringeth forth much fruit: for without me ye can do nothing. 6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. 7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
8 Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
