So this is how we get saved?
The Word always confirms itself:
After listening to Peter and believing that Jesus was the messiah whom was crucified, those present were upset and asked what THEY MUST DO. Peter
DID NOT say, “Nothing else needed. You are good to go; you believe the message. Peter’s response to their question was to give instructions that everyone must follow after believing in the Lord Jesus. The instructions are recorded in Acts 2:36-42:
Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
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?
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.
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.
And with many other words did he testify and exhort, saying,
Save yourselves from this untoward generation.
Then
they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
It is recorded that both Gentiles and Samaritans also followed Peter’s life giving message of belief, repentance, water and Holy Ghost baptism: (Acts 10:44-48; Acts 8:12; 14-17)
Notice Peter’s interaction with the Jewish leaders concerning what the Angel of the Lord told Cornelius, a Gentile, to do. He was told to seek out Peter who would tell thee words (explain)
what he must do to be saved. (Acts 11:13-14)
Why would Peter command that Cornelius and others be water baptized if it was not a part of salvation?: “Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we? And
he commanded them to be baptized in the name of the Lord.” Acts 10:47-48
Lastly, individual disciples at Ephesus were given and received the same message from Paul. (Acts 19) This account specifically points to the fact that water baptism must be done in Jesus name. If water baptism did not play a part in salvation it would not be necessary to re-baptize these disciples in water at all.
Due to the multiple recorded examples one should realize that no individual is exempt from following the command given by God through Peter. Every individual throughout history has been/or is a descendant of one of the groups noted; ie, Jews, Gentiles, Samaritans.
Keep in mind that Peter's instructions included the fact that "...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. I believe it is an accurate statement to say, God is still calling people.
