On God's justice

Do not call God just, for His justice is not manifest in the things concerning you.  And if David calls Him just and upright, His Son revealed to us that He is good and kind.  ‘He is good,’ He says, ‘to the evil and to the impious.’  How can you call God just when you come across the Scriptural passage on the wage given to the workers?...How can a man call God just when he comes across the passage on the prodigal son who wasted his wealth with riotous living, how for the compunction alone which he showed, the father ran and fell upon his neck and gave him authority over all his wealth?  Where, then, is God’s justice, for while we are sinners Christ died for us!
