I can show you easily.
Read what Paul says here:
9
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Paul says to confess/say with your mouth, "Jesus is my Lord".
Now if you think Paul is teaching that is all you have to do is say, "Jesus is my Lord", then you are wrong, for Paul tells us about confessing! More on that shortly. Right now, I want to show you about saying to yourself, or anyone that Jesus is your Lord---
What does the Lord God Jesus say about calling him your Lord, do you know? Let me help you.
Luke 6:46 “Why do you call me, ‘Lord, Lord,’ and do not do what I say?
Matthew 7:21 Not everyone who says to Me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of My Father in heaven.
We can go on to the next things, but do you understand so far?
Not by how you apply Matthew 7:21 as if inferring works to be added in order to obtain salvation.
You have not underlined nor boldened nor highlighted anything in Paul's gospel presentation that requires repenting from all sin or as some others would insists to be water baptized to obtain salvation.
I would emphasized verse 11 since it is by believing in Him is how any one would confess Jesus Christ as their Saviour, right? Indeed, one has to believe in Him for them to call on Him to be saved.
Romans 10:8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11 For the scripture saith, Whosoever believeth on him shall not be ashamed. 12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. 13 For whosoever shall call upon the name of the Lord shall be saved. 14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? 15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! 16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report? 17 So then faith cometh by hearing, and hearing by the word of God.
Chew on that for a while, because they have to be saved in order to call Him Lord.
And as far as Matthew 7:21 goes, that is to any saved believer following Him as His disciples as there can be a point when a disciple refuses correction and continues in iniquity for why he is at risk being cut off for being workers of iniquity.
Note verse 6 in John 15:1-8 below.
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.
Now I tell you, it is not about loss of salvation because the Father chastens those left behind and scourges them too. Look at these saved believers how they are at risk for not resisting sin.
Hebrews 12:1Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin. 5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:
6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. 9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness. 11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
Now look at the stripes from that Father's scourging for having the measure of knowledge they had for not being ready when they get left behind but still whipped as being His servants & this still saved as His?
Luke 12:40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not. 41 Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all? 42 And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? 43 Blessed is that servant, whom his lord when he cometh shall find so doing. 44 Of a truth I say unto you, that he will make him ruler over all that he hath. 45 But and if that servant say in his heart, My lord delayeth his coming; and shall begin to beat the menservants and maidens, and to eat and drink, and to be drunken;
46 The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers. 47 And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. 48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more. 49 I am come to send fire on the earth; and what will I, if it be already kindled?
See the connection? Now why would the Father do that for those left behind unless,,, they were saved and still are simply for believing in Jesus Christ for why they will be resurrected after the great tribulation as vessels unto dishonor.
Why would God have those vessels unto dishonor in His House that did not depart from iniquity? Those vessels of wood and earth testify to the power of God in salvation for all those that believe in Jesus Christ, even in His name.
How else can you explain why the vessels unto dishonor, the vessels of wood & earth, that are in His House for not departing from iniquity other than they were saved by believing in Jesus Christ, even in His name.
