The word
Really, anything. If Jesus sends you to Peets to go get him a coffee, that is—no foolin’—being his apostle. Now, once you’re done, are you still an apostle? Well, that’s debatable… and usually debated vigorously by all the people whom Jesus sent on one mission or another, who now include “apostle” among their titles, and even make it part of their screen names on social media. (He’s not just “Maximilián Bernardi” on Facebook; he’s “Apostle Maximilián Bernardi.” As far as Facebook knows, his full first name is “Apostle Maximilián.” Imagine if gas station attendants did this. But I digress.)
I know; some churches insist the only apostles are the 12 guys Jesus designated when he walked the earth—with a special exception made for Paul, ’cause Jesus appeared to him special. I’d point out
As for why he picked ’em, we have to read this bit first, which makes it kinda obvious:
Mark 3.7-12 NET - 7 Then Jesus went away with his disciples to the sea, and a great multitude from Galilee followed him. And from Judea, 8 Jerusalem, Idumea, beyond the Jordan River, and around Tyre and Sidon a great multitude came to him when they heard about the things he had done. 9 Because of the crowd, he told his disciples to have a small boat ready for him so the crowd would not press toward him. 10 For he had healed many, so that all who were afflicted with diseases pressed toward him in order to touch him. 11 And whenever the unclean spirits saw him, they fell down before him and cried out, “You are the Son of God.” 12 But he sternly ordered them not to make him known.
For those who can’t see the obvious: Jesus was busy. This was a massive ministry he had undertaken. And though he’s Jesus, he’s still just one man; he needed help! He needed apprentices. So he picked 12 of his best students.
Mark 3.13-15 NET - 13 Now Jesus went up the mountain and called for those he wanted, and they came to him. 14 He appointed twelve so that they would be with him and he could send them to preach 15 and to have authority to cast out demons.
Matthew makes it sound like these were his only students, and maybe they were at the time.
Matthew 10.1 NET - Jesus called his twelve disciples and gave them authority over unclean spirits so they could cast them out and heal every kind of disease and sickness.
But Luke indicates they were among his students.
Luke 6.12-13 NET - 12 Now it was during this time that Jesus went out to the mountain to pray, and he spent all night in prayer to God. 13 When morning came, he called his disciples and chose twelve of them, whom he also named apostles…
Luke 9.1-2 NET - 1 After Jesus called the twelve together, he gave them power and authority over all demons and to cure diseases, 2 and he sent them out to proclaim the kingdom of God and to heal the sick.
Jesus chose students to do this, and all his apostles—including present-day apostles—are still his students. Still gotta learn from the Master. But what makes ’em apostles is Jesus designated and sent them to do stuff.
Namely the very same things Jesus did. The same things the crowds were swarming Jesus to get: Cure diseases, drive out their demons, and tell ’em about
It’s all part of Jesus’s ultimate goal: To multiply himself in every Christian. ’Cause we Christians are to do all the stuff he did, and then some.
