`The good man out of the good treasure of his heart doth bring forth that which <FI>is<Fi> good; and the evil man out of the evil treasure of his heart doth bring forth that which <FI>is<Fi> evil; for out of the abounding of the heart doth his mouth speak.
Luke 6:43 `For there is not a good tree making bad fruit, nor a bad tree making good fruit;
Luke 6:44 for each tree from its own fruit is known, for not from thorns do they gather figs, nor from a bramble do they crop a grape.
Luke 6:45 `The good man out of the good treasure of his heart doth bring forth that which <FI>is<Fi> good; and the evil man out of the evil treasure of his heart doth bring forth that which <FI>is<Fi> evil; for out of the abounding of the heart doth his mouth speak.
Luke 6:46 `And why do ye call me, Lord, Lord, and do not what I say?
Luke 6:47 Every one who is coming unto me, and is hearing my words, and is doing them, I will shew you to whom he is like;
The verse centers on "good", "treasure", "heart", "doth", "bring", and "forth". It is saying that the verse draws attention to "good" and "treasure", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 44's "for each tree from its own fruit..." into verse 46's "And why do ye call me Lord...", so "good" and "treasure" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "good" and "treasure" with trust shaped by these words, not by a vague optimism outside the passage.
