In this passage (Matthew 10:1-15), we discovered 4 important elements in Jesus' sending of the 12, which carry over time and space to us today:
1. Jesus chose UNLIKELY candidates. We know of 4 fisherman, a tax collector, and a zealot (a militia-member)! This isn't exactly a collection of the spiritually elite. They didn't know everything about Jesus, they surely didn't understand all his teaching... and yet BAM! He sent them out. It's time for Christians to let go of the concept that "I can't go until I'm ready." Preparation is VERY important, and God will make room for it - but don't disqualify yourself!
