The Biblical Gospel is very simple:
1 Corinthians 15:1-4
King James Version
15 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures
The DEATH / BURIAL and RESURRECECTION of Jesus Christ.
We MUST not only believe the Gospel, but it MUST be applied to our lives…
We DIE with Him in Repentance / We are BURIED with HIM (not them) in water BAPTISM and walk in the newness of life (the New Birth) by the power of His RESURRECTING power of the Holy Ghost.
Romans 6:3-5
King James Version
3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
Jesus’ last words after His DEATH / BURIAL and RESURRECTION, just before He ascended back up to heaven:
Luke 24:45-49
King James Version
45 Then opened he their understanding, that they might understand the scriptures,
46 And said unto them, Thus it is written, and thus it behooved Christ to suffer, and to rise from the dead the third day:
47 And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.
48 And ye are witnesses of these things.
49 And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
Peter preached the 1st message to Jesus’ new Testament Church and instructed the Jews on what to do…[notice Peter preached exactly what Jesus told him to preach]
Acts 2:36-38
King James Version
36 Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ.
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?
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.
