But I have prayed for you, that your faith fail not: and when you are converted, strengthen your brothers. Luk 22:32 Peter was not yet converted and the same was true of all the disciples.     They were in a state of partial belief and partial unbelief.

All of the disciples were only converted or 'saved' on the day of Pentecost when they were filled with the Holy Spirit.   

The Holy Spirit is not optional equipment.   

I indeed baptize you with water unto repentance: but he that comes after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Spirit, and with fire: Mat 3:11 This is John the Baptist speaking about four things    ➛ Water Baptism    ➛ repentance    ➛ Jesus    ➛ Spirit Baptism.      Water Baptism is a sign that the person being baptized is repentant.     Repentance is necessary to access the Grace of the Lord.     Jesus is the object to which we turn toward away from our old ways of thinking, believing and living.      Though John does not mention it here, turning away from the old life to Christ Jesus and confession of Him as the risen Lord confirm our redemption by Grace Rom 10:9,10.      We are redeemed by the sacrifice of Christ Jesus.     Redemption is all on His part.     We add nothing to it.      Once we are Born Again as a result of repentance and faith In Christ Jesus we are to be filled with His Holy Spirit.      We respond to the Gospel of Jesus Christ    ➛ by turning away from unbelief and wickedness    ➛ by believing that Jesus is `God`,    ➛ by receiving Christ Jesus by faith as our Saviour,    ➛ by asking Him to fill us with His Holy Spirit.      Spirit Baptism is the end-game for our existence on earth.         ➛ the Holy Spirit is the Spirit Of Christ in us    ➛ the Holy Spirit seals us to the Lord Jesus.         ➛ Receiving the Spirit Of Christ is intimate union with Jesus.         ➛ the Holy Spirit is Eternal Life in us    ➛ the Holy Spirit in us is our expectation of glory    ➛ the Holy Spirit is power in us to do the supernatural.         ➛ the Holy Spirit is the witness of Christ Jesus in us.

And, behold, I send the promised Holy Spirit Father upon you: but tarry you in the city of Jerusalem, until you be endued with supernatural power. Luk 24:49 Understanding this verse:    ➛ Jesus is giving a command (send)    ➛ A promise is an announcement of potential.         ➛ `my Father` may best be understood as `my generator`.         ➛ The Holy Spirit is the one who generated Jesus.         ➛ Jesus is ordaining His own Spirit to come to us.         ➛ We are to wait for His Holy Spirit to come upon us and fill us before going out in Jesus` name.         ➛ When we are baptized with His Holy Spirit we then have both the authority of Jesus and the power of His Spirit in us.

    1.   Jesus did not come to keep us out of hell.   
    2.   He did not come to cleanse us.   
    3.   He did not come to enable us to live forever.   
    4.   Jesus came to enable us to receive His Holy Spirit and be One with Him.   
1,2 and 3 above are benefits of what He did to enable 4.   

But you are not in the flesh, but in the Holy Spirit, if so be that the Holy Spirit dwell in you.     Now if any man have not the Holy Spirit of Christ, he is none of his. Rom 8:9 The Holy Spirit is the Spirit Of Christ.      The Spirit Of Christ is the Holy Spirit Eph 2:18 Eph 4:4 1Co 12:13 Phi 1:27.      We are In Christ which means we are in His Holy Spirit.     It is His Holy Spirit in us and us in His Holy Spirit that makes us His child.      In the KJV the term Spirit Of God and then Spirit Of Christ is used interchangeably.     This means that the Spirit Of God is the Spirit Of Christ and we know that there is only One Spirit Eph 4:4 1Co 12:13 1Co 6:17.

To whom the Holy Spirit would make known what is the riches of the glory of this mystery among the Gentiles; which is the Holy Spirit in you, the hope of glory: Col 1:27 The Holy Spirit, by virtue of Christ Jesus, has imparted Himself into believers and thereby brought them into His glory as His sons.      We have the same Spirit in us that raised Christ Jesus from the dead.     Rom 8:11 All things are possible to him that believes.     Mar 9:23

The Church is weak because it has not understood what it means to be a Christian.   To be a Christian is to be In Christ.   We cannot be in the physical body of Jesus.   

To be In Christ is to be filled with His Holy Spirit and to abide in His Holy Spirit, to be filled with His Word and to abide in His Word.   

It was never the Lord's plan to just set us free to run around and destroy ourselves once again.   His plan has always been for each of us to be in intimate, personal relationship with Him by receiving His Word and His Holy Spirit as our new identity.   

Peter was converted (saved) when He was filled with the Holy Spirit on the day of Pentecost.   Those who deny the Pentecost experience deny the consummation of the New Birth in the same way that those who deny the Word deny the consummation of the New Birth.   

If you are not In Christ you are on tenuous ground.   You must be filled with Him and be One with Him for Him to recognize you at the Judgment Seat Of Christ.   

And be not drunk with wine, wherein is excess; but be filled with the Holy Spirit; Eph 5:18 One of the fruit of the Spirit is temperance (self control).     Excess is to be avoided in all things but especially in those things which cloud our minds and subject us to Satan`s influence.      Being drunk is being under the influence.     Being sober is being clear headed.     Alcohol and drugs are not the only things that can bring one under the influence of Satan, The Mystery Of God, the Mystery Of Christ is accomplished as we are filled with the Holy Spirit and serve Christ in His power The Holy Spirit IS Eternal Life.     Receiving Him is receiving Eternal Life.     Apart from Him there is only death.      When Jesus talked about giving us life and life more abundantly, He was talking about giving us His Holy Spirit Joh 10:10.
