Please post the relevant Scriptures to benefit us all.
The idea that we need to "work" for Salvation and the indwelling of the Holy Spirit is refuted by a host of Scripture that call on us to believe (too many to post):
Jn. 3:16 - For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Rom. 10:9 - Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.
Jn. 20:31 - But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
Jn. 5:24 - Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
1 Jn. 5:10 - Whoever believes in the Son of God has the testimony in himself. Whoever does not believe God has made him a liar, because he has not believed in the testimony that God has borne concerning his Son.
Jn. 17:20-23 - I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me. The glory that you have given me I have given to them, that they may be one even as we are one, I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.
Jn. 7:29 - Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
Eph. 1:13 - 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,
Gal. 3:2 -
This is the only thing I want to find out from you: did you receive the Spirit by the works of the Law, or by hearing with faith?
Gal. 3:14 -
in order that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we would receive the promise of the Spirit through faith.
I'm aware that there are also a lot of verses that show that water baptism was used - and I think that water baptism is an important part of obedience. However, it's the baptism of the Holy Spirit that's important, the thing that saves us -
Lk. 3:16 -
John answered and said to them all, “As for me, I baptize you with water;
but One is coming who is mightier than I, and I am not fit to untie the thong of His sandals; He will baptize you with the Holy Spirit and fire.
