Writing Referenced in Scripture
Jesus never said that his followers needed to keep a journal. In fact, as far as I know, Jesus didn't keep a journal or even write letters. So keeping a journal is not a requirement of the spiritual life. Nevertheless, the Bible does give us some interesting glimpses of God writing or giving a writing assignment.
God gives a writing assignment to the future israelite Kings
"When he (the king) takes the throne of his kingdom, he is to write for himself on a scroll a copy of this law, taken from that of the priests, who are Levites. It is to be with him, and he is to read it all the days of his life so that he may learn to revere the Lord his God and follow carefully all the words of this law and these decrees and not consider himself better than his brothers and turn from the law to the right or to the left. Then he and his descendants will reign a long time over his kingdom in Israel."
God Himself writes
"At that time the Lord said to me [Moses], 'Chisel out two stone tablets like the first ones and come up to me on the mountain. Also make a wooden chest. I will write on the tablets the words that were on the first tablets, which you broke. Then you are to put them in the chest.'"
The Israelites are to write the commandments on the door frames of their homes
"'Hear, O Israel: The LORD our God, the LORD is one. Love the LORD your God with all your heart and with all your soul and with all your strength. These commandments that I give you today are to be upon your hearts. Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. Tie them as symbols on your hands and bind them on your foreheads. Write them on the door frames of your houses and on your gates.'"
The israelites are to Write on stones taken from middle of the river
"Moses and the elders of Israel commanded the people: 'Keep all these commands that I give you today. When you have crossed the Jordan into the land the LORD your God is giving you, set up some large stones and coat them with plaster. Write on them all the words of this law when you have crossed over to enter the land the LORD your God is giving you, a land flowing with milk and honey, just as the LORD, the God of your fathers, promised you. And when you have crossed the Jordan, set up these stones on Mount Ebal, as I command you today, and coat them with plaster. Build there an altar to the LORD your God, an altar of stones. Do not use any iron tool upon them. Build the altar of the LORD your God with fieldstones and offer burnt offerings on it to the LORD your God. Sacrifice fellowship offerings there, eating them and rejoicing in the presence of the LORD your God. And you shall write very clearly all the words of this law on these stones you have set up.'"
Moses must Write a song for future generations
"'Now write down for yourselves this song and teach it to the Israelites and have them sing it, so that it may be a witness for me against them. When I have brought them into the land flowing with milk and honey, the land I promised on oath to their forefathers, and when they eat their fill and thrive, they will turn to other gods and worship them, rejecting me and breaking my covenant. And when many disasters and difficulties come upon them, this song will testify against them, because it will not be forgotten by their descendants. I know what they are disposed to do, even before I bring them into the land I promised them on oath.' So Moses wrote down this song that day and taught it to the Israelites."
don't just remember, but Write a description of the Promised Land
"As the men started on their way to map out the land, Joshua instructed them, 'Go and make a survey of the land and write a description of it. Then return to me, and I will cast lots for you here at Shiloh in the presence of the LORD.' So the men left and went through the land. They wrote its description on a scroll, town by town, in seven parts, and returned to Joshua in the camp at Shiloh."
an everlasting witness
"Go now, write it on a tablet for them, inscribe it on a scroll, that for the days to come it may be an everlasting witness. These are rebellious people, deceitful children, children unwilling to listen to the LORD's instruction. They say to the seers, 'See no more visions!' and to the prophets, 'Give us no more visions of what is right! Tell us pleasant things, prophesy illusions. Leave this way, get off this path, and stop confronting us with the Holy One of Israel!'"
the day Jesus wrote
"They were using this question as a trap, in order to have a basis for accusing him. But Jesus bent down and started to write on the ground with his finger. When they kept on questioning him, he straightened up and said to them, 'If any one of you is without sin, let him be the first to throw a stone at her.' Again he stooped down and wrote on the ground.
At this, those who heard began to go away one at a time, the older ones first, until only Jesus was left, with the woman still standing there. 10 Jesus straightened up and asked her, 'Woman, where are they? Has no one condemned you?'
'No one, sir,' she said.
'Then neither do I condemn you,' Jesus declared. 'Go now and leave your life of sin.'"
The Words of the Wise are like nails
"The words of the wise are like goads, their collected sayings like firmly embedded nails--given by one Shepherd. Be warned, my son, of anything in addition to them. Of making many books there is no end, and much study wearies the body."
Not Enough Room for all the Words
"Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written."
