Your statement seems to suggest that after salvation, a person can sin and not worry about asking forgiveness for that sin because it was all inclusive with their salvation experience. Problem with that is, Jesus Himself taught us to pray for the forgiveness of our sins WHEN WE PRAY!
In relation to salvation, repentance means to change your mind from unbelief/rejection of who Christ is to belief/acceptance of Christ as God's Son. More specifically placing one's faith in Jesus's sin atoning sacrifice & resurrection.
Ultimately, there is only one sin that Jesus's payment doesn't/won't forgive/pardon: "Unbelief" in & the rejection of, Christ's sin payment & resurrection, until/at life's end/death. (We all die Heb 9:27)
Jn 8:24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
(MY MOTE: You'll die in you sins if you don't repent from everyone? NO! You will die in your sins if you don't BELIEVE in Christ!)
I believe the word repentance is the most misunderstood & misused word in Christianity. Invariably people like you tie repent to every sins. Jesus added thoughts to the law (Matt 5:21-28) good luck controlling/repenting from every single one of them.
Jn 12:32 Jesus said; And I, if I be lifted up from the earth, will draw all men unto me.
(MY NOTE: Jesus was in fact lifted up. Everybody is drawn to/offered salvation via God's Holy Spirit. Sadly, not everyone excepts/embraces it, by FAITH)
Jn 16:
7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
(MY NOTE: The Holy Spirit will reprove/expose/convict everyone of, sins? NO of "SIN" singular.)
9 Of sin, because they believe not on me;
(NOTE: The only SIN that condemns one to eternal separation/damnation is UNBELIEF! Continued rejection of Christ's sin payment & resurrection, until/at life's end. Jesus sin payment covers/includes all sin except rejection of His finished works at life's end/your death)
1 Jn 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
(MY NOTE: Anyone that believes they can conquer their own sin nature, without Gods help is mistaken)
Rom 2:4 Or despisest thou the riches """of his goodness""" and forbearance and longsuffering; not knowing that """the goodness of God leadeth thee to repentance"""?
(MY NOTE: It's thru the GOODNESS of GOD not thru OUR OWN great work of sin repentance, obedience or self-control. That we REPENT/change our thinking/course. It's salvations seal of indwelling Holy Spirit that leads us to REPENT/change our thinking outlook & direction).
Acts 10:44 While Peter yet spake these words, the Holy Spirit fell on all them which heard the word.
(MY NOTE: They Believed (vs43) & as Peter spoke (vs44) The Holy Spirit fell on them (vs45). NO REPENTANCE of any kind here, No water baptism, No circumcision, they brought no sin sacrifice to the Temple, No law keeping etc)
Thru faith & faith alone, placed in Jesus redemptive work & resurrection. These gentiles were given/received the baptism OF & were eternally sealed BY God's indwelling Holy Spirit (vs45) = SAVED - FINISHED TRANSACTION! Also see Eph 1:13, 2 Cor 1:22 & Eph 4:30/sealed until the day of redemption, Rom 8:38-39)
2ndly,
To be clear, neither in this post, nor at any other (I've placed 100's). Have I ever advocated ungodly living or claimed one can sin with impunity.
Nor have I ever said sin doesn't have consequence.
I've said we access righteousness, justification, salvation through faith (Rom 5:1-2) & not thru works (Eph 2:9), obedience, repentance etc.
Sin can bring consequence that may manifest itself, in many different ways. A health issue, a broken relationship, disease, lost rewards earned etc.
A believer's sin will not result in the loss of salvation. Unlike you, I'll provide scripture (1 Cor 3 below) that support my position/belief. BTW, Unbelief is the only unforgivable sin, that can't be cleansed by the blood of Christ.
1 Cor 3:
8 Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.
(MY NOTE: Rewards are given based on work done in Christ's name. Even a drink of water given is His name will receive a reward (Matt 10:42, Mk 9:41 )
11 For other foundation can no man lay than that is laid, which is Jesus Christ.
12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
(MY NOTE: Gold & silver = Good works done in Christ's name. Hay, wood & stubble = no works, selfish works, even bad works)
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
(MY NOTE: Every work good & bad will be tested)
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
(MY NOTE: Good works done in Christ's name will receive a reward)
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
(MY NOTE: Hay, wood & stubble deeds will burn-up, bringing shame & loss = "Of Rewards". Not the loss of one's salvation)
Rereading verse 15: he shall suffer loss: but he himself shall be saved.
Rev 22:12 And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.
Christ bought us/our sins for a price, His sinless life:
Finally, these verses helped shape my belief.
Jude 1:1 Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ
(MY NOTE: Believers/saints are sanctified by God & PRESERVED in Jesus Christ)
Rom 8:
38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
(MY NOTE: Once justified/forgiven nothing can separate a Christian from God’s love)
Rev 1:5 Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto Jesus Christ that loved us, and washed us from our sins in his own blood,
(MY NOTE: When we place our faith in Jesus faithful sin atoning work & resurrection. That ALL our sins are remissed. Also see Col 1:14 & 2:13)
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
(MY NOTE: Salvation is obtained, by God's GIFT of grace = God's unmettited/underserved favor. Thru faith placed in Jesus faithful sin atoning work & resurrection.1 Cor 15:1-4)
Eph 4:32 Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.
(MY NOTE: Written to believers see Col 1:2. Forgive each other as God forgave <PAST TENSE> you.)
Heb 9:12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
(MY NOTE: Christ obtained ETERNAL REDEMPTION for us)
Heb 13:20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant,
(MY NOTE: This new sin management blood covenant is EVERLASTING! Not just 1 year or until the next time to stumble or fall)
Believers sins are forgiven & washed away via an EVERLASTING COVENANT!
2 Tim 1:14 Refers to the Holy Spirit as a Guard & Deposit.
2 Cor 5:5, Eph 1:14 & 2 Cor 1:22. Refer to the Holy Spirit as "the earnest" = Pledge or Promise.
Eph 1:13, 2 Cor 1:22 & Eph 4:30 Refer to the Holy Spirit as a Seal.
2 Tim 1:14 The Holy Spirit who dwells within us, guard the good deposit entrusted to you
(MY NOTE: The Holy Spirit dwelling within us. Is God's deposit & guards us until the day of redemption)
2 Cor 5:5 God, who also hath given unto us the "earnest" of the Spirit
(MY NOTE: God's Holy Spirit dwelling within us is the earnest. Earnest translated from the Greek word: arrabon. Also means a pledge)
2 Cor 1:22 Who hath also "sealed us" & "given the earnest" of the Holy Spirit in our hearts
(MY NOTE: God has placed His Holy Spirit in the believers heart. As a pledge & a SEAL until the soon coming day of our redemption)
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
(MY NOTE: You heard about Christ's finished sin redemptive payment & resurrection. When you believed/trusted, Christ sealed/baptized you with His Holy Spirit).
Eph1:14 Which is the "earnest" of our inheritance until the redemption of the purchased possession
(MY NOTE: The Holy Spirit by which Christ baptizes/seals & indwells us. Is the earnest = a down payment, a pledge, a promise, a guarantee)
Eph 4:30 grieve not the holy Spirit of God, whereby ye are "sealed" unto the day of redemption
(MY NOTE: Believers are SEALED with God's Holy Spirit. It's a pledge, promise, guard & guarantee that Christ will come for us)
Rom 11:29 For the gifts and calling of God are without repentance.
(MY NOTE: God doesn't go back on His Word or Promises)
