John Gill Commentary Luke 14:22

"And the servant said, Lord, what thou didst command is done, and yet there is room." — Luke 14:22 (ASV)

And the servant said
After he had been and brought in a large number of such as are before described, and he was directed to, and succeeded to the gathering of them in:

Lord, it is done as you have commanded ;
the apostles exactly observed the orders of their Lord and master; they began to preach the Gospel at Jerusalem; and being drove from thence, they went and preached to the Jews of the dispersion, and to the proselytes among the Gentiles:

and yet there is room ;
that is, for the Gentiles, after God's elect, among the Jews, for that time were gathered in: there was room provided for them in the heart and love of God from everlasting, and in electing grace; in the suretyship engagements of Christ, in the covenant of his grace; and they had a place in the redeeming grace of Christ, in time; and in the last commission he gave to his disciples; and there was now room for them in the church of God; and will be in the new Jerusalem, and in the heavenly glory.
