If you add anything to salvation, it is no more grace but works and works doesn’t save anyone.
Acts 16:31-34, And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. And they spake unto him the word of the Lord, and to all that were in his house. And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway. And when he had brought them into his house, he set meat before them, and rejoiced, believing in God with all his house.
As you see within the context of these 4 verses, there is a simple outline that leads to salvation. The first thing I see is that a lost person can become a believing person by hearing the Word of God preached. He must hear the Word. He must believe it. And then He gets saved. And that’s the outline. God’s Word is preached. A lost person believes it and they get saved. It’s salvation plus nothing!
Have you heard it? Did you believe it? If so, there will be evidences of it in your life. (2 Corinthians 5:17) The first thing is that you will obey Jesus’ command to be baptized as an outward showing of what has happened in your life. It doesn’t save you or add to your salvation but it will help give you the assurance because you have followed His Word to be baptized.
