Luke 6:12-16 The Selection Of The Twelve. Prayer, And Being Sent.
On this occasion Jesus had to get away from the crowds and so went up to a mountain to pray (v. 12 Cf. Mt. 14:23; Mk. 5:16; 9:18; 11:1). He would also pray early in the morning, no doubt for the same reason (Cf. Mk. 1:35). On this occasion it no doubt had to do with the selection of the twelve which was to follow. In any case, Jesus does leave us an example, though few of us will stay up a whole night to pray. However, this was an important occasion. Clearly Jesus wanted to enlist the twelve in the building of His church and the extension of His cause and kingdom.
It was very important that He Himself select these men to work with Him while He still ministered among them. These were the ones He chose, including Judas who would betray him (cf. 22:3-6; Jn. 6:70). He also called them apostles, since they were also sent out to do His work (Cf. Jn. 20:21). Even so, though we are not apostles as such, we to are also sent by Him to continue this work, as His ambassadors, to speak His word and do kingdom work. To this end, it is very important that we also take the time to pray and seek His help.
