Marking the transition from the introduction to the treatise. “I am ready to preach at Rome, for, though I might seem to be deterred by the contempt in which the Gospel is held, and by the prospect of my own humiliation as its preacher, I am not ashamed of it.” The transition occupies Rom 1:16, Rom 1:17.
The Gospel
Omit of Christ.
Power (δύναμις)
Not merely a powerful means in God's hands, but in itself a divine energy.
First
Not principally, nor in preference to the Greek; but first in point of time. Compare Joh 4:22; Rom 3:1; Rom 9:1; Mat 15:24.
