What in the world is the baptism of the cup? If you have only one idea of baptism, listen to this lesson to learn that there are eight different kinds of baptism in the Bible, three of which involve water, and five are dry. See that the cup of baptism refers to what is in the cup. Find out that when Jesus referred to the drinking of His cup, He is talking about His suffering on the Cross. Since none of us will die on a cross, understand that it refers to the unjust suffering that is part of the spiritual life of all believers. We need to ask ourselves how we handle unjust suffering.
