Here is how Ellen White describes who God is:
1. God is "the all-wise, all-powerful God, He who dwells in light unapproachable, is full of love, of goodness." He is to be glorified for the gift of His Son, Jesus, who intercedes for humanity (See annotation: "The all-wise, all-powerful God, He who dwells in light unapproachable, is full of love, of goodness. Therefore give glory to God, ye that are doubting and trembling; for Jesus lives to make intercession for us. Give God the glory for the gift of His dear Son and that He has not died for us in vain." 5T 633.3).
2. God is a Spirit, but also a personal Being, not merely an impersonal force or energy (See annotation: "God is a Spirit; yet He is a personal Being; for so He has revealed Himself." MH 413.1).
3. God is the embodiment of benevolence, mercy, and love. Those connected with Him will show harmony, love, and unity (See annotation: "God is the embodiment of benevolence, mercy, and love. Those who are truly connected with Him cannot be at variance with one another. His Spirit ruling in the heart will create harmony, love, and unity." CT 90.3).
4. God is the Creator and sustainer of all things. The Bible presents Him as the true, living, and everlasting King, the maker of the heavens and the earth. The Sabbath is a memorial of His creative power (See annotation: "The Lord is the true God, He is the living God, and an everlasting King... He hath made the earth by His power, He hath established the world by His wisdom, and hath stretched out the heavens by His discretion... The Sabbath, as a memorial of God's creative power, points to Him as the maker of the heavens and the earth." PP 336.1).
5. God is the strongest being in the universe, a personal God who created man and is actively involved in the world (See annotation: "God is the strongest being in the universe... Through Jesus Christ, God—not a perfume, not something intangible, but a personal God—created man, and endowed him with intelligence and power." 3MR 326.4).
6. God reigns with majesty but also loves and cares for the most helpless and suffering among His children (See annotation: "God reigns, and notwithstanding His majesty He loves the most helpless, the most suffering ones among His children." 21MR 219.6).
7. God is above all science, the living, personal Author and Ruler of nature, whose knowledge surpasses human understanding (See annotation: "God, the living, personal God, the Author and Ruler of nature, is above all science. He is acquainted with science that is inexplicable to the greatest minds in our world." 3MR 328.1).
