Summary: On three different occasions God literally wrote words for the benefit of certain people. Let us see what importance there is in those events.
WHEN THE FINGER OF GOD WRITES IT DOWN
All the Bible is the inspired Word of God, but there are specific times when Jehova wanted to make a very strong point.
3 times we find that God literally wrote with His own finger
18 And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God. (KJV)
18 Y dio a Moisés, cuando acabó de hablar con él en el monte de Sinaí, dos tablas del testimonio, tablas de piedra escritas con el dedo de Dios. (RVG04)
The Ten Commandments
Sins which God will not put up with.
Not 10 suggestions, 10 rules that God established for His people. These are to be a pattern for our lives.
No other gods---We have a holy and jealous God.
Don't take His name in vain. That is more than just not cursing.
Keep Sunday holy. It is a day of rest.
Honour your parents---that is more than obeying them.
No adultery. One night stands outside of marraige or taking anothers spouse for the long term.
Do not lie.
The law makes us conscious of sin. By it, we know what God hates and for what He will judge us.
5 In the same hour came forth fingers of a man's hand, and wrote over against the candlestick upon the plaister of the wall of the king's palace: and the king saw the part of the hand that wrote. (KJV)
5 En aquella misma hora salieron unos dedos de mano de hombre, y escribían delante del candelero sobre lo encalado de la pared del palacio real, y el rey veía la palma de la mano que escribía. (RVG04)
26 This is the interpretation of the thing: MENE; God hath numbered thy kingdom, and finished it. (KJV)
26 Ésta es la interpretación del asunto: MENE: Contó Dios tu reino, y le ha puesto fin. (RVG04)
This king thought nothing of the law of God, thus God judged him.
IL.: The Bear and the Athiest
One cannot ignore the law of God and get away with it. Sooner of later, judgment will be your lot.
7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. (KJV)
7 No os engañéis; Dios no puede ser burlado; pues todo lo que el hombre sembrare, eso también segará. (RVG04)
The Man who couldn't hide his sin.
A man went on a business trip. He invited a woman to his motel room and committed adultery. As she left late that night, he smiled to himself and thought, "well I got away with this one, no one will ever find out what I have done". The next morning he walked into the bathroom and saw a message on the mirror in red lipstick---Welcome to the world of Aids. You can run but you will never hide from God. He will judge sin and the sinner.
III. MERCY AND FORGIVENESS
This woman was guilty and caught in the very act. There were eyewitnesses.
It is interesting that the man was not brought in also. After all, it takes two to tangle. Rules of society and culture are not always fair.
She was forced to stand in front of all in this cruel "mock trial"
Possibly, she already knew who Jesus was.
