Baptism saves us through the resurrection of Jesus Christ. All spiritual blessings such as salvation, prayer, being a Christian are found in Christ. Baptism is what puts us into Christ. There are no spiritual blessings before baptism. Baptism is where we come in contact with the death of Jesus.
Baptism is a burial.
We cannot be in the likeness of Christ's resurrection, if we have not been planted in the water of baptism. Those who are not baptised were not because they did not believe. When we find out we need to be baptized, we are not to tarry.
