1Pe 3:19 By which also he went and preached unto the spirits in prison;

Baptism can be bypassed if it is no fault of the person,as the thief on the cross,but the Bible says baptism does now also save us,and Mark said he who believes and is baptized shall be saved.
There are some dangerous pratices out there,confessing sins to a priest,and then is it effective,baptism is not essential for salvation,so some will bypass it for it does not matter to them,sin does not affect their relationship with God,so some people hold unto sins thinking they are alright,and then the blood of Christ cannot wash it away.
