Romans 1:15
So, as much as in me is, I am ready to preach the gospel to you that are at Rome also.Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.
Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus.
Not boasting of things without our measure, that is, of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly, To preach the gospel in the regions beyond you, and not to boast in another man's line of things made ready to our hand.
