"But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness?" (2 Peter 3:10-11, emphasis mine)
Elementary
Stone. Paper. Metal. Paul says "ye are our epistle written in our hearts, known and read of all men." (2 Corinthians 3:2) In other words, those to whom Paul was writing had lived in the words and ideas and, really, the presence of God transmitted through his anointed writings. So much so that they had become something of a walking testimony. But that's the whole idea. So whether you're obeying the ten commandments as unto the Lord or drawing a cross on the sidewalk with a piece of bark or anything at all involving the word of God, virtual or analog, it flows back to Jesus. He's the Living Word.
"This they said, tempting Him, that they might have to accuse Him. But Jesus stooped down, and with His finger wrote on the ground, as though He heard them not." (John 8:6)
Have you ever carved your name in the trunk of a tree? How about tagged a building with spray paint? What about poetry in journals or etching your initials on concrete? There's a desire to leave our mark. To graphically represent a piece of information—whether it symbolizes us or merely one part of us—that is encoded onto our being. Evidently Jesus was literate and able to write, too. I assume He was writing things about the Pharisees standing by. Things that He knew, and while He wouldn't have been inclined to spread abroad, were in the air, so to speak. Things in their nature that hadn't been absolved in spite of all their rules and regulations. Things the Father could point to as infractions. I've gone on now long enough in speculation. What did He write? God knows. It's one of those mysteries of the New Testament that, while we don't have an exact answer, can intuit through the context.
"So when they continued asking Him, He lifted up Himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again He stooped down and wrote on the ground." (John 8:7-8)
Writ large
I remember reading once that graphology was evil. The article said that it was on the spectrum of divination and as such should be avoided. Really, any trick you would use to try and get a bead on anyone so as to understand things about them you have no business knowing, is not good, not of God. This being said, however, I find it fascinating to observe the way people do their letters. I have a Japanese neighbor and the way she scratches the little lines of hiragana and kana is simply wonderful. The complex kanji even more so. The time we take to make our words legible truly does tell on a deep level—and then on a grand scale (consider the place from which fonts come and are designed: it's called a "foundry"). Because it's what's going on inside our head. I have several ways of writing (when I'm not typing). This doesn't mean I'm schizophrenic, just that I have moods. Upper case, lower case. Script, because I don't write in italics. I love all of it. I have the gift of expression through letters. Thank God.
"Looking for and hasting unto the coming day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?" (2 Peter 3:12)
Slow down. Life is a gift. So too is expression. Fonts are like dressing for the mind, so practice your letters. When I was a kid, my dad inculcated time and again the slow, deliberate forming of my alphabet. I hated it at the time because my mind was all over the place. But now, everytime I put implement to element, I joy and rejoice a little inside. Because I feel the care way down deep. And the more time and care I take penning what's on my heart, the more you'll care to read it. This is my hope.
