PAY CAREFUL ATTENTION: We are so accustomed to the term ‘second coming,’ and have the conclusion of the ‘first coming’ in mind as we read the Ascension story in Acts 1, but we must be careful not to read anything of the kind into Paul’s thinking. People read the gospels and assume, incorrectly, that Paul was informed by them.
