I have heard several biblical counselors use the following story to teach about the true source of our sinful anger.
If you are holding a cup and I bump your arm and so the contents spill out on the floor, what caused the spill? You might be inclined to blame me. It wouldn’t have spilled except that you bumped me. But, really, the only reason why it spilled is that you had contents in your cup. If the contents weren’t in the cup, it wouldn’t spill no matter how hard I bumped into you. When we get sinfully angry, it is easy to blame the other as the cause. In reality, the true source of sinful anger is the one who is expressing it. The one who bumps is not the cause, only the situation that uncovers what was already there
This little analogy finds its basis in the book of James (3:9f)
With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God’s likeness. Out of the same mouth come praise and cursing. My brothers and sisters, this should not be. Can both fresh water and salt water flow from the same spring? My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water
Origins of the cup story?
But, where did this cup story find its origin? In all of the times I heard this little story, I never heard it attributed to someone. As a result, I assumed it originated with someone in the biblical counseling movement.
While I still do not know the FIRST time it was used, I can tell you that it appears in Amy Carmighael’s little book, IF, published first in the 1930s. I have an undated copy of the book (published by CLC). Page 37 says this,
If a sudden jar can cause me to speak an impatient, unloving word, then I know nothing of Calvary love.*
*For a cup brimful of sweet water cannot spill even one drop of bitter water however suddenly jolted.
Is this the origin? Anyone know if someone before the 1930s used this example?
