In baptism, you die to sin, and live in Christ.
Therefore, you haven’t lived, until you’ve died.
There is life after death, in this life.
Romans 6:4,7 (KJV) – therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in the newness of life. For he that is dead is freed from sin.
