It is encouraging to realize that Jesus did not call those twelve disciples who became apostles on the basis of their innate worthiness or personal capabilities or faithfulness, but solely on the basis of what He could make of them by His own power working through them. It is a mark of authenticity and honesty that the gospel writers, like all the other Scripture writers, make no effort to mask the faults and shortcomings of God's people, including those of their most outstanding leaders. During the disciples' three years of training under Jesus, we see few signs of maturity and reliability but many signs of pettiness and inadequacy. It is a marvelous insight into the grace of God toward us to see Christ dealing so lovingly and patiently with men who are so weak and unresponsive. . . .
