Can you prove the holy Spirit is God?
2. The holy Spirit is expressly called Jehovah, a name that is utterly incommunicable to all creatures, and which can be applied to none except the Great Supreme. It was Jehovah who spoke by the mouth of all the holy Prophets from the beginning of the world (Luke 1:68, 70), yet in 2 Peter 1:20 it is implicitly declared that those Prophets all spoke by "the Holy Ghost" (see also 2 Sam. 23:2, 3, and compare Acts 1:16)! It was Jehovah whom Israel tempted in the wilderness, "sinning against God and provoking the Most High" (Ps. 78:17, 18), yet in Isaiah 63:10 this is specifically termed, " they rebelled, and vexed his holy Spirit:"! In Deuteronomy 32:12 we read, " So the LORD alone did lead him," yet speaking of the same people, at the same time, Isaiah 63:14 declares, " the Spirit of the LORD caused him to rest: so didst thou lead thy people, to make thyself a glorious name. " It was Jehovah who bade Isaiah, " Go, and tell this people, Hear ye indeed " (6:8, 9), while the Apostle declared, "Well spake the Holy Ghost by Esaias the prophet unto our fathers, Saying, Go unto this people, and say, Hearing ye shall hear ..." (Acts 28:25, 26)! What could more plainly establish the identity of Jehovah and the Holy Spirit? I also need to note that the Holy Ghost is called "the Lord" in 2 Thessalonians 3:5.
3. The perfections of God are all found in the Spirit. By what is the nature of any being determined but by its properties? He who possesses the properties peculiar to an angel or man is rightly esteemed one. So He who possesses the attributes or properties, which belong alone to God, must be considered and worshipped as God. The Scriptures very clearly and abundantly affirm that the holy Spirit is possessed of the attributes peculiar to God. They ascribe to Him absolute holiness. As God is called "Holy," "the Holy One," being therein described by that superlatively excellent property of His nature wherein He is "glorious in holiness" (Ex. 15:11); so is the Third Person of the Godhead designated "the spirit of holiness" (Rom. 1:4) to denote the holiness of His nature and the Deity of His Person. The Spirit is eternal (Heb. 9:14). He is omnipresent: "Whither shall I go from thy spirit? or whither shall I flee from thy presence?" (Ps. 139:7). He is omniscient (see 1 Cor. 2:10, 11). He is omnipotent: being termed "the power of the Highest" (Luke 1:35; see also Micah 2:8, and compare Isa. 40:28).
