Your comments cannot be serious? I have never read anywhere in the Bible, where anyone speaks of being told about entering the "promised millennial kingdom"! The verb ἀγωνίζομαι is used for a contest, in which much effort is made, and is contrasted with ζητέω (seek), which is for a casual desire! Jesus in Matthew, which is the corresponding passage to Luke, says, "
13“
Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many.
14For the gate is
narrow and the way is hard that leads to life, and those who find it are few." (7). Are you saying that "Narrow Way" that Jesus says, "leads to life", is not "eternal life"? Regardless of theology, and any difficulty in the passage in Luke, it is very clear, that the sinner is NOT "passive", as some assume, in their salvation!
