The Incommunicable Attributes of God
Theologians commonly distinguish between the communicable and incommunicable attributes of God. The communicable attributes of God are those attributes which man and God have in common. For example, both man and God are able to be just, love, show mercy, have knowledge. On the other hand, the incommunicable attributes of God are those perfections which are not shared with others, like His triune nature, eternity, Immutability, absolute sovereignty, omnipresence, omnipotence. God's attributes are God's perfections and excellencies. They are the things which shine forth His glory and majesty.
The Singularity Of God
The Bible is clear on the fact that there is but one God. The Scriptures are manifold proving this in both Testaments. The doctrine of the Trinity is monotheistic and Christianity is at the core monotheistic. In Mark 12:29, the Lord Jesus quotes Deuteronomy 6:4 saying that the most important commandment “is this: 'Hear, O Israel: The Lord our God, the Lord is one.’" The Lord Christ Himself affirmed the doctrine of monotheism, which teaches that there is but one Being of God. Isaiah 43:10 is definite in its affirmation of monotheism:
“You are my witnesses,” declares the LORD, “and my servant whom I have chosen, that you may know and believe me and understand that I am he. Before me no god was formed, nor shall there be any after me.
Before Yahweh, there was no other god and after Him, there shall be no other god. He is the only God that exists and He is but one God. We will also come back to this point in paragraph 3 when we will discuss the doctrine of the Trinity, which teaches that although there is but one Being of God, yet this Being exists in three Persons.
The Lord our God is described as a living God, that implies that He is active and interacts with the world. He is not a god who set up the world and left it on its own. Rather, He is the living God Whose providence guides every step. The expression “living God” is used 28 times in the Scriptures, which implies the activity of God in this world, and it is also an expression against the dead idols of the heathen. In Leviticus 26:30, the Lord warns Israel if they go astray to serve idols saying: “And I will destroy your high places and cut down your incense altars and cast your dead bodies upon the dead bodies of your idols, and my soul will abhor you.” Their bodies will be cast upon the dead bodies of their idols. They will be just like their idols with whom they provoked Him to anger—dead.
He is not only the singular and living God, but He is also the true God. He is the only God that exists and He is likewise truthful. He is the “God of truth” (Isa. 65:16). The expression “true God” is used 5 times in the Bible (2Chron. 15:3; Jer. 10:10; John 17:3; 1Thess. 1:9; 1John 5:20), and it is often connected with God being a living God. Jeremiah 10:10 declares, “But the LORD is the true God; he is the living God and the everlasting King. At his wrath the earth quakes, and the nations cannot endure his indignation.” To say that God is the living and true God is to separate Him from the idols. Paul writes of the Thessalonians and of all Christians that we “turned to God from idols to serve the living...
