I am the light, John 12:46

In the Bible there are many mentions to the light. The teaching of the lamp in Mark 4: 21-23 and Luke 8:16-18; the parable of the lamp in Luke 11:33-36, the healing of a man born blind John 9.
In Metaphysics the light, the truth, the good belongs to the genre of the being instead the darkness, the lie to the genre of non-being. It is logical to attribute to the divine that which belongs to the first genre, that is, to what it is.
The light represents the knowledge that iluminates internally all men.Knowledge should be not hidden. Ignorance is a form of oppression.
The light as perfection of God can be interpreted also as eternal life, nobody can walk in darkness.
Also the light is related with the truth:"But whoever lives by the truth comes into the light", John 3:21
At last in the Bible the light is related with the idea of Gnosis, the ilumination by the grace of God, the ilumination as gift of God: "Everyone will be salted with fire" Mark 9:49.

It is God's will that you should be sanctified, 1 Thessalonians 4:3

The first letter to the thessalonians is a book of the new testament wrote by the apostle Paul. The epistle begins with an invocation to the Holy Spirit and with a thanksgiving. To continue then with an exhortation to holiness and finishing the letter with a mention to the second coming of Jesus Christ.
The apostle emphasizes the expression: "It is God's will that you should be sanctified, 1 Thessalonians 4:3"
The apostle adds: "God has not called us to impurity, but in holiness, 1 Thessalonians 4:7" In this context the concept of holiness is the opposite to impurity and being the impurity a work of the flesh (Galatians 5:19-21), the holiness could be understood as a fruit of the spirit (Galatians 5:22-23).
The apostle in this letter also refers the sanctity as a belonging to the divine, to the spiritual gift of fear of the lord or serenity, this gift is known as constancy, firmness, devotion, ecuanimity, stability. when he affirms: "in order to please God, 1 Thessalonians 4:1".

Good thoughts, good words, good deeds, Zarathustra

Zarathustra is primarity known in western countries for the written book: "Thus spoke Zarathustra" by Nietzsche.
He probably lived before the Achaemenian dinasty (600 to 330 bc) he was a philosopher and also prophet of the persian religion, the zoroastrianism.
He is credited with the autorship of some books: the gathas and the avesta. Zarathustra in his teaching emphasizes the righteousness and the way of thinking, unlike the christian fate that emphasizes the love and the feelings.
His most famous teaching is:

True Friends have one soul, Aristotle

Aristotle wonders about the nature of happiness, and in this study of happiness he focuses in three elements that identifies as keys for the happy man: the virtue, in special justice, the friendship and the pleasure.
Let's talk about the second: the friendship. Aristotle in his book Nichomaquean Ethics, Book VIII wrote about friendship: "is the most necessary for life. In effect, without friends nobody would want to live......But friendship is not is not only necessary but beautiful. We praise those who love their friends and having a lot of friends is considered one of the best things".
Then he affirms: "the happy life is considered to be the life according to virtue."
For what is exposed for Aristotle we can say that needing the man of the virtue for his social activity, and being the friends those with whom we primarity exercise the virtue; friendship is not the foundation of happiness, but without it (friendship) man can not achieve happiness. Friendship is necessary but not sufficient. We need both friendship and virtue.

I am the door, John 10:9

The teaching: "I am the door, John 10:9"; has a relationship with John 1: "In the beginning was the Word, and the Word was with God, and the Word was God". Jesus personifies the door, the door means the word of God, the wisdom of God. Every road starts with a door.
The path of Rectitude starts with the wisdom of God, with the word of God, the science of the divine. In the old and new testament the word of God is identified with the head of science and the intelligence: "For the lord gives wisdom: from his mouth come knowledge and understanding", Proverbs 2:6
The concept of Word of God does not match with the Aristotelian concept of Wisdom (Book of Metaphysics). The Word of God is in direct relationship with the faculties of the spirit: the intuition and the inspiration; 1 Corinthians 2:13 :"This is what we speak, not in words taught us by human wisdom but in words taught by the spirit"
Thomas Aquinas explains and this is important that the Bible is not the word of God, the bible is a book inspired by the word of God, by the counsel of God, because the Word of God predates the existance of man, the Word of God is eternal, is increated. Remember the expression in the Genesis that is similar to John 1.

His works are perfect, Deuteronomy 32,4

The expression:"He is the Rock, his works are perfect, and all his ways are just. A faithful God who does no wrong, upright and just is he", Deuteronomy 32:4; is in the song of Moses.
Deuteronomy means in greek "second law", is a book of the Old Testament; the last book of the Pentateuch (Genesis, Exodus, Leviticus, Numbers, Deuteronomy). The autorship of this book is attributed to Moses.
The affirmation: "His works are perfect" has implications is Christian Theology; although God is the wisdom itself, we know God through his works. Tomas Aquinas affirms: in God are present the perfections of all things, Question 4, About the perfection of God.
This is the starting point of the doctrine of the kingdom of God, remember the teaching of Jesus: "Be perfect, as your heavenly father is perfect", Matthew 5:48. It is called perfect to what, of what it requires its perfections, nothing lacks, Thomas Aquinas, Summa Theologiae.
As work of God we are called to his likeness, to the completeness, to the conformity to Jesus Christ.
