Theme Number 9 Evidences of the Infilling of the Holy Spirit

Act 2:4  And they were all filled with the Holy Spirit and began to speak in other languages as the Spirit gave them ability to speak out.


First or Initial Evidence
2:4 They began to speak in other languages {tongues] as the Spirit gave them ability to speak out. This has been called the Initial Evidence of the Infilling of the Spirit.

The Initial Evidence by Rueben A. Hartwick#
The Assemblies of God Constitution and Bylaws, Article V, Statement of Fundamental Truths, reads as follows:
Paragraph 8: The Initial Physical Evidence of the Baptism in the Holy Ghost
The baptism of believers in the Holy Ghost is witnessed by the initial physical sign of speaking with other tongues as the Spirit of God gives them utterance (Acts 2:4). The speaking in tongues in this instance is the same in essence as the gift of tongues (1 Corinthians 12:4-10,28), but different in purpose and use.
Glossolalia
The word glossolalia is made up of two Greek words: glosso meaning “tongues,” and lalia meaning “speech.” Consequently, we use the term, “speaking in tongues.” On the Day of Pentecost what the disciples were saying was understood by about 15 different peoples in their own dialect or language. This was not an ecstatic “out of the body” experience. They were aware of their surroundings. Though an unknown language to the speaker, glossolalia can be a recognized or unrecognized language to the hearers. In 1 Corinthians 13:1, Paul writes, “If I speak in the tongues of
men and of angels. …” He also says of speaking in tongues, “Anyone who speaks in a tongue does not speak to men but to God” (1 Corinthians 14:2). Consequently on the Day of Pentecost, the visitors to Jerusalem heard the newly Spirit-baptized disciples “declaring the wonders of God” (Acts 2:11). Jesus had said in John 16:13-14, “When he, the Spirit of Truth comes, … He will bring glory to me. …” Glossolalia is not used for evangelizing, since later that same day, Peter preached his famous sermon — perhaps inspired speech taking the form of a word of prophecy — in the language that all of them understood (Acts 2:14).

The Infilling of the Spirit
"FATHER" BENNETT, Episcopalian:
...(I) was speaking in an Episcopal church, when a woman came
up and said, 'Father Bennett, I'm so glad you came to explainthese things to us. 
When I was confirmed, many years ago, when
the Bishop put his hands on my head, I just filled up with God,
and began to speak another language. I didn't know what it
meant, and neither did the Bishop.
He told me to stop:' Well, we cannot blame the Bishop too much,
but how sad that the very manifestation that caused the old
sorcerer, Simon Mogus, to offer Peter money to buy the gift,
should have been so forgotten in the church that they create
consternation and puzzlement when experienced, and are
immediately suppressed."
The testimony of AN EPISCOPALIAN PRIEST, as related by "Father"
Bennett:
"I received the Holy Spirit many years ago while in seminary.
There were three of us ready for graduation and ordination. We
knew we didn't have the power of the Gospel, so we went down to
the local Full Gospel Assembly and received the Holy Spirit. We
nearly got thrown out of seminary, but the reality of it has been
with me all my life." Barnett, Donald Lee. "Speaking in tongues." (1989).
Applications.
1. Have you been Filled with the Holy Spirit since you believed? This is the day to be filled.
2. Wait in God’s Presence for the Coming upon or the Anointing of the Spirit with Speaking in Tongues in Your Life today. This is what happened in the early Church.
