Albert Barnes Commentary Romans 15:25

"but now, I [say], I go unto Jerusalem, ministering unto the saints." — Romans 15:25 (ASV)

But now I go etc. I am about to go now. The mention of this intended journey to Jerusalem is introduced in several other places, and is so mentioned that Dr. Paley has derived from it a very strong argument for the genuineness of this epistle. This intended journey is mentioned in Acts 19:21, Paul purposed in the spirit, when he had passed through Macedonia and Achaia, to go to Jerusalem, saying, After I have been there, I must also see Rome. See also Acts 20:2-3. That he went to Jerusalem, according to his purpose, is recorded in his defence before Felix (Acts 24:17), Now after many years, I came to bring aims to my nation, and offerings.

To minister to the saints. To supply their necessities by bearing the contribution which the churches have made for them.

Paley's Horae Paulinae, chapter 2, no. 1. g. go unto Jerusalem (Acts 19:21).
