Water Baptism
We follow the after the Apostles and the way they followed after what Jesus taught. They were the eyewitnesses after all and Jesus picked these men of strong constitutions for a reason.
The book of Acts in every instance where baptism was performed, the apostles baptized in the name of Jesus Christ.
Immediately after explaining the plan of salvation in the 38th verse of acts in the 39th verse of the 2nd chapter of Acts, Peter said
“this promise is unto you and your children and to all them that are afar off.”
It is not for just a certain time period but rather a generation after generation promise. This means it is meant for you and me.
