When we are obedient to the gospel, when we believe and are saved we are called to be baptised.
For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile.
What does the Bible say?
1 Cor 15:1-4
Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
For what I received I passed on to you as of first importance[a]: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures,
Paul was reminding them of the gospel, death, burial and resurrection of our Lord Jesus. The wages of sin is death, but Jesus paid it, taking the punishment of our sins, so we can have eternal life. Without Jesus' death, we would be doomed to eternal punishment.
It is Good News to us.
1 John 4:10
This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins.
1 Cor 6:14
By his power God raised the Lord from the dead, and he will raise us also.
The death of Christ is just as important as his resurrection. A habit we can fall into is trying to fix up a person who never died, was buried and raised up, "the old man".
Jesus said to her,
We have to be obedient to the gospel of God.
1 Cor 13: faith, hope and love
Foolishness of man, cut a tree and made one part and idol and burnt the other half for fuel (Isa). Gospel is death, burial, resurrection of our Lord
Sin is the opposite of obeying our Father in heaven.
God is after the new person, born of the Spirit.
When we turn around and accept Jesus, we should get baptised, its part of the deal. Its a commandment. Jesus was baptised before he began his earthly ministry. Part of being born again is being baptised. We also need to be part of a family, if we don't become part of Gods family we are orphans.
For we know that our old self was crucified with him so that the body ruled by sin might be done away with,that we should no longer be slaves to sin—
When we obey the gospel of Christ, we are no longer slaves to sin. God has paid the price to make you free!
But thanks be to God that, though you used to be slaves to sin, you have come to obey from your heart the pattern of teaching that has now claimed your allegiance.
We are going to be a slave to something, right or wrong?
Without repentance there is no forgiveness of sin.
When we get baptised, bury old self, sin and new person raised up.
Obey righteousness. God calls you to walk in the light. Don't pick up your sin.
God makes us righteous not ourselves. We are buried (die), and are resurrected to life. Representation of what God has done.
As we have already said, so now I say again: If anybody is preaching to you a gospel other than what you accepted, let them be under God’s curse!
God paid a big price for us to be saved
Our place in all of this is to Grow Up and be mature people, who are able to do his work. Tell people about the gospel.
