Every generation has their own cultural language. These slang sayings or words provide unique ways to communicate with people your own age. When I was younger, if you said something outlandish, you would likely hear someone in the crowd say, “you’re full of it.” This expression refers to being unreliable or ridiculous (usually due to making unfounded or nonsensical statements).
For physical training is of some value (useful for a little), but godliness (spiritual training) is useful and of value in everything and in every way, for it holds promise for the present life and also for the life which is to come. 9 This saying is reliable and worthy of complete acceptance by everybody, 1 Timothy 4:8-9.
As I have grown older and wiser, I am not as vocal as in my younger years. Rather than speak prematurely, I tend to sit back and observe my surroundings. As a listener, it’s easier to see the character of those who you interact with or work side by side. Over time you’ll be able to extract what inside other human beings. Or as the apostle Paul suggests in the passage above, what are you full of?
For the Word that God speaks is alive and full of power [making it active, operative, energizing, and effective]; it is sharper than any two-edged sword, penetrating to the dividing line of the [g]breath of life (soul) and [the immortal] spirit, and of joints and marrow [of the deepest parts of our nature],exposing and sifting and analyzing and judging the very thoughts and purposes of the heart. 13 And not a creature exists that is concealed from His sight, but all things are open and exposed, naked and defenseless to the eyes of Him with Whom we have to do, Hebrews 4:12-13.
A first century doctor makes an interesting observation while listening to Jesus speak. On this particular day, people came from all over Judea and Jerusalem and to seacoast of Tyre and Sidon. Near the end of his speech, Jesus reveals that human beings speak out of the overflow of their heart. Whatever is inside of you, will come out eventually, the good and the bad, Luke 6:45. In view of this reality, the next tell you open your mouth, be cautious as what are you full of will soon be revealed.
