God’s Unity – One Lord The Shema of Deuteronomy 6:4 declares God’s numerical oneness: “The LORD is one.” He is the only true God, unrivaled and incomparable (Isa. 45:5). This truth anchors biblical faith in monotheism and protects against the worship of false gods. The New Testament affirms this same unity, with Paul writing, “There is one God” (1 Tim. 2:5). God’s Simplicity – Not Made of Parts God’s simplicity means He is not composed of separate parts. His attributes are no

God’s immutability means He never changes in His essence, character, purpose, or promises. “I, the LORD, do not change” (Mal. 3:6). Though creation shifts and people falter, God remains constant. His unchanging nature anchors faith, ensures His Word stands forever, and guarantees His promises. For believers, His immutability is a source of stability, hope, and assurance in a world of constant change.

God’s Self-Existence Defined When God revealed His name to Moses, “I AM WHO I AM” (Exod. 3:14); He declared His self-existence. He is not caused, created, or dependent. John 5:26 affirms this same truth: “The Father has life in Himself.” Everything else borrows existence, but God simply is. His aseity distinguishes Him from all created beings and makes Him the fountain of all life. Creation’s Dependence on God While God is independent, all creation depends entirely on Him. Pa

When believers learn these names, they are reminded that God is not distant but has revealed Himself personally and relationally.

God’s names reveal His character and relationship to His people. As Adonai, He is Lord, the sovereign ruler over all creation. As Tsur, He is the Rock, unshakable and dependable. As Ab, He is Father, caring for His people with covenant love. Each title assures believers of His authority, strength, and intimacy, fulfilled perfectly in the Father of our Lord Jesus Christ.

He is never surprised, never rushed, and never bound by clocks or calendars.

God reveals His character through His names. Compound forms of Yahweh—such as Yahweh-yireh (The Lord Provides), Yahweh-nissi (The Lord Is My Banner), and Yahweh-shalom (The Lord Is Peace)—show how He meets the needs of His people. These names assure believers of His presence, provision, victory, and peace. Through Christ, each promise tied to these names is fulfilled for God’s people today.

The name Elohim, used over 2,000 times in Scripture, emphasizes God’s supreme power and majesty. Appearing in Genesis 1:1, it presents Him as Creator and sustainer of all things. Though plural in form, the name reflects the fullness of His power and hints at His triune nature. Elohim declares that God is strong, sovereign, and mighty to save, ruling over creation and history with unmatched authority.

The cosmological and teleological arguments highlight God’s power and wisdom: creation demands a cause, and design implies a designer. Yet these arguments, when detached from Scripture, fall short. Many have used them to defend false gods. Only the Bible reveals the true Creator, who is both the First Cause and the purposeful Designer. In Christ, we see not only order in creation but redemption for sinners.

For centuries, thinkers have argued for God’s existence using reason—ontological, cosmological, teleological, and moral proofs. While these point to design and order, they cannot lead to the saving knowledge of the true God. Scripture teaches that reason alone is insufficient because fallen humanity suppresses the truth. Only God’s self-revelation through His Word and Spirit opens blind eyes to see Him.

The Limits of Human Effort Paul explains that fallen humanity “suppresses the truth in unrighteousness” (Rom. 1:18). The natural mind is hostile toward God and unable to grasp His truth (1 Cor. 2:14). Though creation testifies clearly to His existence, sinful man distorts this witness, exchanging the glory of the Creator for idols (Rom. 1:23). No philosophical reasoning or moral striving can overcome this blindness. Apart from God’s intervention, humanity remains lost in igno

God Exists Beyond the Boundaries of Time Time is one of God’s creations. Genesis 1:1 records the beginning of all things: “In the beginning, God created the heavens and the earth.” Before that moment, only God existed. Unlike creatures who are bound by beginnings and endings, God is timeless—“the eternal God is a dwelling place, and underneath are the everlasting arms” (Deut. 33:27). His name revealed to Moses, “I AM WHO I AM” (Exod. 3:14), declares His timeless being. He is

While God can be truly known, He can never be fully comprehended. The Bible affirms both His knowability and His mystery. His greatness surpasses human intellect, and His thoughts are higher than ours (Isa. 55:9). We know Him through His Word and Spirit, but our understanding is always partial. This humbles us, teaching that worship begins where human reasoning ends—with reverent trust in the infinite God.

Day 15 of our 30-day study focuses on the doctrine of God, emphasizing His holiness and sovereignty. Scripture reveals the majesty of God’s character, setting Him apart as holy and ruling over all creation. Doctrine teaches us to tremble in awe and rest in His sovereign rule.
