And this gospel of the kingdom shall be preached in all the world for a witness unto all nations

                                                     

What is the gospel?

It is the Good News that Jesus died for our sins, was buried, and rose from the dead on the third day, so that we could turn from our sinful way, bury our sinful nature by baptism in the name of Jesus, and arise to walk with Jesus with a new life, filled with His Spirit!

"Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; by which also ye are saved if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures:" - 1 Corinthians 15:1-4

We are saved by the gospel – the death, burial, and resurrection of Jesus – if we OBEY the gospel.

"Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me." - Matthew 16:24

We deny ourselves by repenting of our sins. We take up our cross by crucifying our sinful nature. We follow Jesus in His burial by being water baptized in the name of Jesus. We follow His resurrection when we are filled with His Spirit and walk in a new life.

"What shall we say then? Shall we continue in sin, that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein?  Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? 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." - Romans 6:1-4

Peter preached the gospel on the Day of Pentecost, then how to obey the gospel.

"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." - Acts 2:38-39
