Trainableness

But we must not forget that it was important for Jesus in many respects to form a small circle around Him very early, at a time when a great choice was not afforded Him (Matt. ix. 37, seq.), that Jesus must have regarded chiefly moral and intellectual trainableness, and that the final result of His training of the disciples (especially when we remember the turn which the Christian affairs took through the instrumentality of Paul) neither depended upon Him alone, nor even—if He did not possess omniscience (which even in John ii. 25, is certainly not attributed to Him)—could with certainty be foreseen.

Look at the trainableness of animals. How sad to see a brute of a man driving an intelligent horse.

Each child served as his or her own control to minimize genetic effects of trainableness between students.
