If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?
Christ The Giver of The Holy Spirit
(Matthew 3:11)

Through waiting upon God

And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
