Answer:
B. Lincoln includes the motif of God to reveal his main point; God's will reigns supreme
Step-by-step explanation:
Lincoln starts by quoting Jesus' words in Woe unto the world because of offenses! for it must need to be that offenses come, but woe to that man by whom the offense cometh.’ (Mathew 18:7 KJV)
And then He starts making a comparison to that offense Jesus alludes to slavery. Then Lincoln proceeds to say that as God was there God is with them. So God is still supremely commanding the course of History.
