““And He [Jesus] went up on the mountain and called to Him those whom He desired, and they came to Him. And He appointed twelve (whom He also named apostles) so that they might be with Him and He might send them out to preach.” This important decision of calling the apostles was not a casual event. Jesus got away from the regular occupation of His ministry to give proper attention to this selection.
While the twelve Apostles (capital “A”) were special, it was only in the sense that they were used by the Holy Spirit to launch the Early Church from Jerusalem. In another sense, we should all be apostles (small “a”) as messengers of the gospel to go and “make disciples of all nations” (Matthew 28:19). Jesus did not call you just to rescue you from a lost eternity, but it was a special call to be His ambassador in a lost world (2 Corinthians 5:17-20), just as He called the twelve.
Further, Jesus has “appointed” you as He did the twelve. That word means you have been “assigned to a task that must be performed”. At the end of Mark’s gospel, he comments that the apostles “went out and preached everywhere, while the Lord worked with them” (16:20). As you and I see the importance of our calling and appointment, we will be obedient to proclaim Christ everywhere, whether in our private lives, marriage, family, workplace or in ministry.
So what is the ONE THING NECESSARY? “That they might be with Him”! Jesus knew that their effectiveness and ours would only be accomplished through a close relationship with Himself. If you seek this ONE THING, Jesus will make you effective in every area of life through the Spirit.
