Nowadays in the West there is often not a great price to pay for the act of being baptized, there is of course the risk of being alienated by friends and family but in the 1500’s, when adult baptism by immersion was first practised by those who saw that infant baptism or sprinkling was not Biblical, the price was high.
What is water baptism?
It is the sign of the covenant that the born again believer enters into with the Lord, similar to the engagement ring given to a bride.
The sign of the covenant that God made with Israel in the Old Testament was circumcision. The sign of the new covenant that the Lord has made with the body of Christ, the Church is water baptism.
