Charles Spurgeon Commentary Romans 1:13

"And I would not have you ignorant, brethren, that oftentimes I purposed to come unto you (and was hindered hitherto), that I might have some fruit in you also, even as in the rest of the Gentiles." — Romans 1:13 (ASV)

Ah! Paul, you could not go when you wished. Caesar must convoy you.

Your Master intended for you to go to Rome under the protection of the eagles of your empire. God has servants everywhere: he can make Satan himself provide the bodyguard for his faithful apostle's journey.
