I just wanted to talk a little about the holy ghost because not everyone knows what it is.... The word, "ghost", in the Bible is also translated as, "spirit", in some places. Both words are translated from the Greek word, "pneuma", meaning spirit. The holy spirit, or holy ghost, is the spirit of God. God accompanies three offices.... He is God (the father), Jesus is God in the flesh (the son), and the holy spirit is the spirit of God. The gift of the holy spirit is a promise from God. Once you are baptized for the remission of sins, God will baptize you will the infilling of his spirit. Acts 2:4 defines the holy spirit..."All of them were filled with the Holy Spirit and began speaking in other tongues". So does Isaiah 28:9-12: "Very well then, with foreign and strange tongues, God will speak to this people". Acts 2:38 says, "Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins and you will recieve the gift of the holy spirit. The promise is for you and your children and for all who are far off, for all whom the Lord our God will call." John the Baptist ,quoted by all four Gospel writers, that Jesus would baptize them with the holy ghost. God's word is very precise in giving us examples of this phenomenal sign of speaking in tongues as evidence one has recieved the holy ghost. Acts 2:1-4, Acts 8:1-25, Acts 10:44-48, Acts 19:1-6 Joel 2:28-29 and Acts 2:16&17 - God's promise of the holy ghost is to all flesh- sons, daughters, servants, and handmaids. Many people speak out against the holy spirit, saying that it's fake, or that it's just a way to bring people to the church, all I can say in response to that is this... Mark 3:28-30 says that, "I tell you the truth, all the sins and blasphemies of men will be forgiven, but whoever blasphemes against the holy spirit will never be forgiven, he is guilty of an eternal sin". There are three basic and important reasons for the Spirit of God to dwell within each christian 1) It is necessary for salvation (romans 8:9-11, I corinthians 12:3) 2) It will lead us into all truth (john 16:13) 3) It acts as a discerner and intercessor (romans 8:26) In John 14:16, Jesus says, "I will ask the Father and he will give you another counselor to be with you forever - the spirit of truth. The world cannot accept him because it neither sees him or knows him. But you who know him, for he lives with you and will be in you".... In Acts 1:8 Jesus says, "But you will receive power when the holy spirit comes on you"... Acts 15:13 says, "May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the holy spirit." I corinthians 14:21 says, "Through men of strange tongues and through the lips of foreigners, I will speak to this people but even then they will not listen to me", says the Lord". When you are filled with the holy spirit and you speak in tongues, you are speaking your mind to God. Basically, When you pray out loud, satan is able to hear you, and your deepest fears. When you speak in tongues, you are speaking secrets to God. Only God knows what you are saying because he has given you the gift. 1 peter 1:12 "It was revealed to them that they were not serving themselves, but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the holy spirit sent from heaven. Even angels long to look into these things" satan is a fallen angel, and since the angels cannot speak in tongues, neither can he. He cannot interpret what your saying.
