Your Baptism in the Holy Spirit is received by faith. Receiving the Holy Spirit is so important to the believer being equipped to fulfill his purpose and destiny in God.
Luke 11:13 If you then, evil as you are, know how to give good gifts [gifts that are to their advantage] to your children, how much more will your heavenly Father give the Holy Spirit to those who ask and continue to ask Him! Acts 2:4 And they were all filled (diffused throughout their souls) with the Holy Spirit and began to speak in other (different, foreign) languages (tongues), as the Spirit kept giving them clear and loud expression [in each tongue in appropriate words].Romans 8:26-27 So too the [Holy] Spirit comes to our aid and bears us up in our weakness; for we do not know what prayer to offer nor how to offer it worthily as we ought, but the Spirit Himself goes to meet our supplication and pleads in our behalf with unspeakable yearnings and groanings too deep for utterance. And He Who searches the hearts of men knows what is in the mind of the [Holy] Spirit [what His intent is], because the Spirit intercedes and pleads [before God] in behalf of the saints according to and in harmony with God’s will.
