Adam Clarke on Romans 15:32

That I may come unto you with joy - That his apprehensions of ill usage were not groundless, and the danger to which his life was exposed, real, we have already seen in the account given of this visit, Acts 21, 22, 23, and 24; and that he had such intimations from the Holy Spirit himself appears from Act 20:23; Act 21:11; Act 20:38. Should his journey to Jerusalem be prosperous, and his service accepted, so that the converted Jews and Gentiles should come to a better understanding, he hoped to see them at Rome with great joy: and if he got his wishes gratified through their prayers, it would be the full proof that this whole business had been conducted according to the will of God.
