“And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance” (Acts 2:4).
As new leaders were sought in the early Church, Peter said: “Wherefore, brethren, look ye out among you seven men of honest report, full of the Holy Ghost and wisdom, whom we may appoint over this business” (Acts: 6:3). This means being full of the Spirit is discernible. From the text, we deduce that you can tell if someone is filled with the Spirit. The next question is how?
Repeatedly in the Epistles, an important piece of information is communicated about the infilling of the spirit of God. It is demonstrated by ‘speaking.’ Paul instructed the church at Ephesus (Eph 5:18-19), to not be drunken with wine, but rather to be filled with the spirit, SPEAKING to themselves in psalms.
Today’s text says “…they were all filled with the Holy Ghost and began to speak with other tongues” (Acts 2:4). In Acts 4:8, the Bible says: “Then Peter, filled with the Holy Ghost, said unto them…” We see the same thing in Acts 4:31. The bible says: “And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness”.
Many think one who is full of the Spirit is moody and doesn’t to anyone. But a lot of talking and rejoicing comes with being filled, especially talking in tongues as we see in Acts 2, 10 and 19.
