From the beginning of the church, at Pentecost, Peter issued an invitation to baptism, affirming the promise is for you, for your children and all who are far away. (Acts 2:39) In 1 Peter 1:1-9 we find God has given us a new birth into a living hope through Christ's resurrection. Therefore, our response should be one of love for Christ and belief in him. Note the theme of grace and faith in this passage.
Would it be fair to say that baptism is one outward sign of an inward and spiritual grace? Is there a connection between baptism and salvation?
