Yet, the following states the repentence comes before we even get the Holy Spirit.
Acts 2:38
Peter replied, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.
I've already explained this, but let's go through it again. The Holy Spirit, the Spirit of Christ, is God's voice in the world and becomes God's voice within us. The Holy Spirit commonly works through believers, because if they've asked for Him through the prayer of faith, then God gives Him in accordance with His word, the promise of the Holy Spirit, not just God with us, but God in us. Do you understand the distinction?
Jesus said that when He left, that He would send the helper, the Spirit of Truth, also called the comforter, the Spirit of Christ, the Holy Spirit, and the different names, like the different names for God in the old Testament, describe what He does, not just who He is.
15 “If you love Me, keep My commandments. 16 And I will pray the Father, and He will give you another Helper, that He may abide with you forever— 17 the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you. 18 I will not leave you orphans; I will come to you. John 14:15-18
What else did Jesus say about the "job" of the Holy Spirit?
25 “These things I have spoken to you while being present with you. 26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you. John 14:25-26
So teaching us and making us remember His word (in order to apply it in some fashion) is His job, not ours.
But Jesus said more about His return in the person of His Spirit:
Nevertheless I tell you the truth. It is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I depart, I will send Him to you. 8 And when He has come, He will convict the world of sin, and of righteousness, and of judgment: 9 of sin, because they do not believe in Me; 10 of righteousness, because I go to My Father and you see Me no more; 11 of judgment, because the ruler of this world is judged.
12 “I still have many things to say to you, but you cannot bear them now. 13 However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come. 14 He will glorify Me, for He will take of what is Mine and declare it to you. 15 All things that the Father has are Mine. Therefore I said that He will take of Mine and declare it to you. John 16:7-15
One purpose in sending the Holy Spirit is specifically to convict the world of sin and maybe you're missing this or maybe you're not, but everyone is born into the world. Everyone starts out born in the kingdom of darkness, born to flesh, born to a carnal nature, and not automatically a disciple of Christ. The gospels tell us that He picked those disciples closest to Him, and it wasn't because of what they did in life, but simply according to His choice (He chose Judas, Judas didn't choose Him. Judas was a thief and a liar.)
Now, how could anyone choose to repent of sin without first being convinced of the truth and convicted by His Spirit?
Isn't the conviction of sin the application of truth to our hearts and through the knowledge of sin, which came (to the Jews) through the law?
What part did we play in that, other than believing and Who made us to believe, according to His election, according to His grace?
These are doctrines as old as the first century. I didn't make them up, but a certain church did a great deal to suppress them.
No one even seeks Christ unless God calls him first. How is that our choice, our will, our work?
For we have previously charged both Jews and Greeks that they are all under sin.
10 As it is written:
“There is none righteous, no, not one;
11 There is none who understands;
There is none who seeks after God. Roman's 3:9-11
We don't seek Him, He seeks us. That's God's work, not ours.
How do you repent from sin and turn to Christ if you aren't looking for Him?
Now, people tend to misuse and misapply the epistle to the Hebrews because it was written by an elder to the Jewish believers born under the covenant of law. Their error is that they've forgotten or ignored the context of the letter and the context of the biblical passages within the letter, but what does it say?
again He designates a certain day, saying in David, “Today,” after such a long time, as it has been said:
“Today, if you will hear His voice,
Do not harden your hearts.”
8 For if Joshua had given them rest, then He would not afterward have spoken of another day. 9 There remains therefore a rest for the people of God. 10 For he who has entered His rest has himself also ceased from his works as God did from His. Hebrews 4:7-8
This letter actually addresses the idea of adding works to your salvation. On the 7th day of creation, God ceased from His work and rested. That's the rest which God's people are meant to enter and you'll notice that verse 8 refers to the one who works ceasing from his works to enter His rest.
What you need to decide is whether you've entered that rest by faith or if you're still trying, like those Hebrews, to add something to God's work by your own effort. Are you putting to death the deeds of the flesh through His effort, resting in Him and trusting Him as the bride is to trust in her husband?
These are not overly complicated passages, but our fear and doubt, our faithlessness, takes what is written for our salvation and turns it into doubt and self condemnation. That isn't God's work, that's Satan's work.
6 Therefore I remind you to stir up the gift of God which is in you through the laying on of my hands. 7 For God has not given us a spirit of fear, but of power and of love and of a sound mind. 2 Timothy 1:6-7
In context this is about performing the work of ministry, but verse 7 is a simple statement of truth to encourage the minister. The fear of God is the beginning of wisdom, but the love of God is its culmination.
17 Love has been perfected among us in this: that we may have boldness in the day of judgment; because as He is, so are we in this world. 18 There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love. 19 We love Him because He first loved us. 1 John 4:17-19
51 Jesus said to them, “Have you understood all these things?”
They said to Him, “Yes, Lord.”
52 Then He said to them, “Therefore every scribe instructed concerning the kingdom of heaven is like a householder who brings out of his treasure things new and old.” Matthew 13:51-52
