Fulness of the Gentiles vs. Times of the Gentiles
As indicated by the post title, I will focus on what Paul meant when he said, "the fulness of the Gentiles". However, there is often confusion when one considers another phrase that Jesus mentioned in Luke 21, namely, "the times of the Gentiles", which I will also clarify in this post. Before we analyze these phrases, lets read the scripture passages to get the proper setting and context.
Luke 21:20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. 21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. 22 For these be the days of vengeance, that all things which are written may be fulfilled. 23 But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people. 24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
Romans 11:24 For if thou wert cut out of the olive tree which is wild by nature, and wert grafted contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be grafted into their own olive tree? 25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27 For this is my covenant unto them, when I shall take away their sins.
