Doctrine-Infused Speech

I was reading my daily Spurgeon this morning when a particular line grabbed me:

We may judge of the secrets of the soul by their manifestation in the man's conversation.

Wow. I have to ask myself, does the truth of Scripture grip me in this way, that my conversation shows my understanding of the Gospel? When I am pressed by the heat of situations or encounter others who struggle, do I promote the truths of the Gospel with my speech? I confess that I do not. Spurgeon also, in quoting 3 John 3, states that "doctrines simply held as creed are like bread in the hand," while if that bread is eaten and digested, it does nourishment (and so too with doctrine).

I've commented on this before, but what we feed on (intellectually and spiritually) determines what we produce with our mouths as well as how we act. We can be a tool of both reproof and encouragement to our brothers and sisters in Christ but also be a stumbling block and detriment to the Gospel in how we speak and act (see James 3:8).

What "secrets" does your conversation with others reveal? Are they the secret treasures of the Gospel or does your talk display something else? May our minds be permeated by the Gospel and its doctrines and may we hold them as dear as life.
