Verses 1 – 7 form one complex sentence. This makes me wonder what they were thinking when they assigned verse numbers to Scripture. As Paul starts this letter, he identifies himself. Why is important for Paul to be known as he has described himself here?
In calling himself a servant or slave to Christ, he draws a line between the two kingdoms, which he will go into more detail in chapter 6 as he teaches that there is no neutral zone in the spiritual realm (Gal 1:10). In claiming to be called to be an apostle he is establishing his authority to instruct the church (1 Cor 9:1). What qualified a man to be called an apostle and why is it important? (Acts 1:15-22)
