Acts 1:26 And they cast their lots, and the lot fell on Matthias. And he was numbered with the eleven apostles.
Whilst we do not know the exact way in which the Apostle Matthias was chosen, the fact remains it was some form of balloting; be it up to God or up to the other apostles.
God chosen these men because they were willing to put aside their own lives they had grown up expecting and take on the life Jesus had shown them.
As we move forward in our lives with God, we too should be willing to give up our own expectations and live for Christ instead.
This may be a hard act to follow if you have always lived with many luxuries, but trusting God means He will give you what you need to do His bidding.
