Worship Elements: Baptized in Christ (Romans 6)

The apostle Paul exhorts us to walk in the Spirit as people who have moved from death to life in Christ.  He also exhorts us to walk in light of our baptism moving us from death to life in Christ.  Is Paul teaching that as one receives baptism that one necessarily receives the Holy Spirit?  Why would Paul use such strong language regarding baptism? 

No Insight without New Birth (John 3:1-15 (LD 20; COD Head 3/4 Article 11)

The interaction between Christ and Nicodemus communicates that there is a problem.  It is a problem with the human condition and not a problem with the Lord.  We can understand on one level the complexity of redemption, but on the other level we fail to see how complex it is.  Nicodemus is shocked by the proposal of a new birth because Nicodemus hears that he needs to be part of another family or another genealogy.  Christ is telling him that this is partly true, but it is not a genealogy tied to a family in this world.  So, what genealogy matters?  What genealogy do we want to have?  How do we attain this genealogy and the necessary birth?
