When Does Holy Spirit Come To A Person?

"That if you confess with your mouth. 'Jesus is Lord,' and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.... For Everyone who calls on the name of the Lord will be saved." [Romans 10:9,10,13] "... So the Son of Man must be lifted up, that everyone who believes in him may have eternal life" [John 3:14, 15] "... That whoever believes in him shall not perish but have eternal life." [John 3:16]
"Whoever believes in him is not condemned..." [John 3:18]

Baptism is an instruction to follow & a desire to give your testimony, not a condition required for salvation:
... Not for the soldier who recognizes his need for the Saviour in a foxhole
... Not for a condemned prisoner who is led to Christ in a cell block
... Not for the terminally ill patient who prays and repents in their hospital bed
... Not for the thief hanging on the tree next to Jesus who was promised "today you will be with me in paradise"
... And not for anyone who accepts the gift of grace offered by Christ's sacrifice.
Yes, we should get baptised, but salvation is not contingent on it.

The moment you give your heart to Christ, He sends the Holy Spirit to reside in and with you, fulfilling the promises that we will never be alone and that the counselor and comforter will be sent.
The Holy Spirit can move in you and through in accordance to the Father's will, and you can be "baptised by the Spirit", but even if you have not experienced a whole-blooded life-altering pentecostal revelation. If you've accepted Christ as your Savior, you too are a Spirit-filled" Christian.

The Holy Spirit is the third person in the Trinity.It is God manifesting Himself to a person He chooses.After this happens He will teach that person things and bring all things to his/her remembrance like it says in the gospel of John ch 14 v 26.The Holy Spirit will reside inside you forever after that baptism.
As to when,plz read the gospel of John ch 14 v15-16.
So obey the commandments and acknowledge the Most High and He will reveal Himself to you.Some people live their entire lives and never have that happen to them.
When it does happen it is the single greatest thing that could happen in the life of a person.It surpasses any pleasure that you have ever experienced.It is akin to when neo in the matrix was unplugged from the illusion that is the matrix.
One last thing.When this happens to you plz listen to what the Holy Spirit says because those words are life.Follow what He says to the letter and you will never go astray.

The answer is a varied as the person asking. Those that are open to a Spiritual experience, who have faith are more likely to have the Holy Spirit come in presence or in mind. It is a wonderful feeling, and can give us much hope for our future, a beautiful feeling of well being. Contact me for more information on being open to the Spirit, Divine or God..

I believe the Holy Spirit may speak to a person at any time. When you feel a prompting to accept Christ you can know that is the Holy Spirit and it may be the first time He has spoken to you. When you accept Christ you receive the Holy Spirit as an advocate. Christ promised the Comforter>

When a person is old enough, usually over 8-12 year's old, and really believe's and understands the Bible and makes the decision to become a Christian you are to be Baptized in water by total immersion which represents being buried into Christ. You must be totally immersed and have, I believe three witnesses observe your confession of belief, your total immersion and when you come up out of the water you receive the gift of the HOLY SPIRIT, from that point on you always have the HOLY SPIRIT with you, but you can also fall away from Christ and lose the HOLY SPIRIT and your Salvation, but I do not have enough time right now to continue writing, sorry!.

The Holy Spirit has came upon me during worship and in times I didn't expect you just never know when Gods ready to have a word with you :)

As soon as you give you life to God.
