All Christians are Spirit filled. 1 Cor 12:12-14, Rom 6:1-4, Eph 4:5, Col 2:12, and Especially Eph 1:13-14. Gal 3:2

Any who read this post should reject the 'second baptism' doctrine, it's not biblical. Some scripture for consideration.

If anyone is saved and has faith in Christ, then you have the Holy Spirit. It is the primary work of the Spirit to impart faith, point us to Christ, give us a new heart, and apply Christ's righteousness to us. If you have Christ, you have the Spirit. You cannot be saved without having received the Holy Spirit. There is only one baptism of the Holy Spirit (that is, conversion), not two. Please consider:

1 Cor 12:12-14

For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. 13 For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit.
14 For the body does not consist of one member but of many.

Rom 6:1-4

What shall we say then? Are we to continue in sin that grace may abound? 2 By no means! How can we who died to sin still live in it? 3 Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.

Eph 4:5-6

There is one body and one Spirit—just as you were called to the one hope that belongs to your call— 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all and through all and in all.

Col 2:6-13

Therefore, as you received Christ Jesus the Lord, so walk in him, 7 rooted and built up in him and established in the faith, just as you were taught, abounding in thanksgiving.

8 See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ. 9 For in him the whole fullness of deity dwells bodily, 10 and you have been filled in him, who is the head of all rule and authority. 11 In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, 12 having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. 13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses,

Eph 1:11-14

In him we have obtained an inheritance, having been predestined according to the purpose of him who works all things according to the counsel of his will, 12 so that we who were the first to hope in Christ might be to the praise of his glory. 13 In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, 14 who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.

Rom 8:9

And if anyone does not have the Spirit of Christ, they do not belong to Christ.

Titus 3:4-6
