The second compressed parable of the two trees springs from the former naturally, as stating the general law of which Luke 6:42 gives one case, namely, that good deeds (such as casting out the mote) can only come from a good heart (made good by confession of its own evils and their ejection). It is often said that Christ's teaching is unlike that of His Apostles in that He places stress on works, and says little of faith. But how does He regard works? As fruits. That is to say, they are of value in His eyes only as being products and manifestations of character. He does not tell us in this parable how the character which will effloresce in blossoms and set in fruits of goodness is produced. That comes in the next parable. But here is sufficiently set forth the great central truth of Christian ethics that the inward disposition is the all-important thing, and that deeds are determined as to their moral quality by the character from which they have proceeded.
Our actions are our self-revelations. The words are not to be pressed, as if they taught the entire goodness of one class of men, so that all their acts were products of their good character, nor the unmingled evil of another, so that no good of any kind or in any degree is in them or comes from them. Theymust be read as embodying a general truth which is not as yet fully exemplified in any character or conduct.
In Luke 6:45 the same idea is presented under a different figure--that of a wealthy man who brings his possessions out of his store-house. The application of the figure is significantly varied so as to include the other great department of human activity. Speech is act. It, too, will be according to the cast of the inner life. Of course, feigned speech of all sorts is not in view. The lazy judgment of men thinks less of words than of deeds. Christ always attaches supreme importance to them. Intentional lying being excluded, speech is an even more complete self-revelation than act. When one thinks of the floods of foul or idle or malicious talk which half drown the world as being revelations of the sort of hearts from which they have gushed, one is appalled. What a black, seething fountain that must be which spurts up such inky waters!
