This Is Something Every Christian Should Do

Baptism is the biblical way in which we show that by the power of the Spirit, we died to our old way of life through the death of Jesus, and live a new life through the resurrection of Jesus, cleansed from our sin in the same way that water cleanses us from filth.  Therefore, being baptized  does not make someone a Christian.  Not being baptized does not cause someone to stop being a Christian.  But a Christian should be baptized.
