God's plan for our salvation is laid out before us in scripture. Religion does not save you, a relationship with Jesus does.
9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. 11 As Scripture says, “Anyone who believes in him will never be put to shame.”12 For there is no difference between Jew and Gentile—the same Lord is Lord of all and richly blesses all who call on him, 13 for, “Everyone who calls on the name of the Lord will be saved.”
16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but to save the world through him. 18 Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.
Believing in the name of Jesus and what He did for us on the cross is the beginning of your transformation. We must repent of our sins and be baptized, fully submerged in water, in the name of the Father, Jesus and the Holy Spirit.
Matthew 28:19 – Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.
Water baptism was the first thing believers did in the early church after they believed in and confessed Jesus as Lord of their life.
