What is baptism with the Holy Spirit?

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. (1Cor 12:13, ESV)

The Holy Spirit baptize us into the body of Christ. Before rebirth we are outside of the body of Christ. We are strangers to God and His new life in Christ. We are not part of God and His people. We are not part of Christ. We are not united in His death and resurrection. We are not part of the flock who are shepherded by the good Shepherd. When we are born again, the Holy Spirit indwell is fully and baptize us spiritually into the body of Christ. The baptism of the Holy Spirit makes as children of God. We drink of the same Spirit that indwell us.

Baptism with the Holy Spirit is rebirth. It is when you become a child of God and the Holy Spirit indwell you and make you part of God’s people. It is not a separate event. There is NO command in the Bible to be baptized with the Holy Spirit. No human being can also give it to another person. It is Jesus who baptize with the Spirit when He save you. The only command about the Holy Spirit in the Bible is to be filled with the Spirit or be controlled by the Spirit. You become filled with the Spirit when you allow the Holy Spirit who is already in you to take control of the complete you. This is also a process and is part of the road of sanctification. How can you be filled with the Spirit when you are still selfish and practice certain sins. The self must be broken down and sin must be overcome. After you become a child of God, you must commit to a road of sanctification. A daily process of repentance and submit to the control of the Holy Spirit.

And do not get drunk with wine, for that is debauchery, but be filled with the Spirit, addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart, (Eph 5:18-19, ESV)

The idea of wine is used because of its controlling nature. When you drink to much wine, it take control of you and determine your behavior. In the same manner, be filled with the Holy Spirit and let the Spirit take control of you and fill you inner most being.

Gill Commentary:

be filled with the Spirit, as with wine, or instead of it, or in opposition to it, when the love of God is shed abroad in their hearts by the Spirit, which is compared to wine, for its antiquity, purity, and refreshing nature; and they are filled with it, who have a comfortable sense of it, and a firm persuasion of interest in it, and are delighted with the views of it, and are as it were inebriated with it; and they are filled with the Spirit, in whom his grace is a well of living water, and out of whose belly flow rivers of it; and who have a large measure of spiritual peace and joy, expressed in the following manner.
