Sin is cosmic treason. Sin is treason against a perfectly pure Sovereign. It is an act of supreme ingratitude toward the One to whom we owe everything, to the One who has given us life itself. Have you ever considered the deeper implications of the slightest sin, of the most minute peccadillo?
— R.C. Sproul, The Holiness of God

Names say something about the one who bears them. Our God has a name – Yahweh (“I am who I am”).

Exodus 3:13-16 – “Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” God said to Moses, “I am who I am.” And he said, “Say this to the people of Israel, ‘I am has sent me to you.’” God also said to Moses, “Say this to the people of Israel, ‘The Lord, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is my name forever, and thus I am to be remembered throughout all generations.”

Our God, Yahweh, is a Spirit, infinite, eternal, and unchangeable, in his being, wisdom, power, holiness, justice, goodness, and truth.

Our God, Yahweh, is the only living and true God. There are three persons in the Godhead; the Father, the Son, and the Holy Ghost; and these three are one God, the same in substance, equal in power and glory.

Our God, Yahweh, made all things of nothing, by the word of his power, in the space of six days, and all very good. He created man male and female, after his own image, in knowledge, righteousness, and holiness, with dominion over the creatures.

The providence of our God, Yahweh,  toward man in the estate in which he was created, was the placing him in paradise, appointing him to dress it, giving him liberty to eat of the fruit of the earth; putting the creatures under his dominion, and ordaining marriage for his help; affording him communion with himself; instituting the Sabbath; entering into a covenant of life with him, upon condition of personal, perfect, and perpetual obedience, of which the tree of life was a pledge; and forbidding to eat of the tree of knowledge of good and evil, upon the pain of death.

Our first parents being left to the freedom of their own will, through the temptation of Satan, transgressed the commandment of Yahweh in eating the forbidden fruit; and thereby fell from the estate of innocency wherein they were created.

Our God, Yahweh, having, out of his mere good pleasure, from all eternity, elected some to everlasting life, did enter into a covenant of grace, to deliver them out of the estate of sin and misery, and to bring them into an estate of salvation by a Redeemer.
