The Church was established in the book of Acts. No other place in the Bible will you find the complete plan of Salvation in its entirety. Matthew, Mark, Luke and John are called The Gospels, (meaning good news). They tell of the divine virgin birth of Jesus, his deity, miracles and the calling of his disciples to carry His message to the world. The books from Romans through Jude are to Churches that were established in the book of Acts. These books were like maintenance manuals dealing with specific problems and encouragement to these churches. Revelations is also called The Revelation of Jesus Christ.
There were Three Feasts that God commanded to be observed.
The second feast was to commemorate the giving of the Law on Mount Sinai. It was fifty days after the Feast of the Passover. This feast was called the Feast of Pentecost, also called feast of weeks, of wheat harvest and first fruits. Pentecost means fifty. When the Law was given on Mount Ras Sufsafeh-Jebel Musa in the Sinai mountain range, there was smoke, fire and the mountain melted and ran down. There was a sound as of a loud trumpet. The Lord God was getting their attention.
Jesus died on the cross during the celebration of the first feast. He arose from the dead and taught his disciples an additional 40 days after his resurrection and before his ascension.
Acts 1:2 Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:
Acts 1:3 To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
Acts 1:4 And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.
Acts 1:5 For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.
Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth
AGAIN GOD DEPLOYS HIS SPIRIT AS A RUSHING MIGHTY WIND
It was no surprise to his disciples when on the Day of Pentecost, (the feast that commemorated the giving of the law, or first covenant, on Mt. Sinai), that the second covenant was ushered in with loud sound as of a rushing mighty wind. Nothing would get the attention of fishermen like the sound of a rushing mighty wind!
The first covenant was ushered in with the sound of a trumpet exceedingly loud. There was smoke, fire, the mountain melted and run down. These were signs that something special was happening.
On the day of Pentecost there were also similar signs, cloven tongues, like as of fire, loud noise as of a rushing mighty wind. You may ask why do similar signs not happen when someone receives the Holy Ghost today? This was for a sign of the new covenant. Mount Sinai did not melt and run down, except on the one time when the first covenant was given. Neither did the mountain melt and run down each time that the covenant was read or enacted.
Acts 2:1 And when the day of Pentecost was fully come, they were all with one accord in one place.
Acts 2:2 And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
Acts 2:3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
Acts 2:4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
This was the new covenant that is still in effect today. The complete plan of salvation was given by Peter when asked, “what shall we do?”
Acts 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Acts 2:37 Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
Acts 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins , and ye shall receive the gift of the Holy Ghost.
The Comforter, which is the Holy Ghost or the indwelling Spirit of the Almighty God, is still being poured out today. The plan of Salvation is the same as when it was explained on the day of Pentecost. Repent, be baptized in the name of Jesus Christ, and receive the Holy Ghost.
Acts 2:39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
