WHAT IS THE GOSPEL?

What exactly do Christians mean when they talk about the “gospel of Jesus Christ”? Since the word “gospel” means “good news,” when Christians talk about the gospel, they’re simply telling the good news about Jesus. It’s a message from God saying, “Good news! Here is how you can be saved!” That’s an announcement you can’t afford to ignore. 
Why Baptism?
Baptism is the first step of obedience for the Christian, as it displays the gospel and allows us to profess our faith in Jesus publicly. In the act of baptism, we unite by faith in the death and resurrection of Jesus. Baptism is for anyone who has been transformed by the power of the Holy Spirit after hearing the gospel and wants to profess Jesus as Lord. The Bible teaches that new Christians are baptized into a local faith family which connects its practice to church membership.
