And He went up on the mountain and called to Him those
He Himself wanted. And they came to Him.
Then He appointed twelve,  that they might be with Him
and that He might send them out to preach,
and to have power to heal sicknesses and to cast out demons…

Mark 3:13-15

Jesus called His disciples and us for four reasons:

1) Because He wanted us

2) To be with Him

3) To preach

4) To have authority over sickness and demonic forces

When you put it that way — it’s a really sweet deal.

1) He picked us — not for our beauty, but because of HIS beauty.

2) Our primary duty: Spend time with Jesus

3) Our calling: Preaching through our lives, careers, relationships and words

4) our authority: Unlimited. We have been given the same authority as Christ
  to do the same works as Christ, by the same power of the Holy Spirit.

Awesome.
