God declares himself throughout the scriptures. He is omniscient, knowing everything. God is omnipresent, able to be anywhere and everywhere, aware at the same time. He is omnipotent: having unlimited power; able to do anything. King David of Israel, in Psalms 139, declares God to be all this and more.
Look at Colossians 1: 9-17. For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding; That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God; Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness; Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: in whom we have redemption through his blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist.
23 God is and was and is to come and makes himself and his resources available to those who choose to take him at his word and do it.
In Exodus 3, when God was speaking to the human Moses about the children of Israel, he declared himself to be I Am That I Am. This speaks of his existence beyond the understanding of time and reminds them who he was to their fathers while pointing to who he will be to them in the future. We know that he created the earth and all that is in it and believe before time was, he was. In Revelations 1:8, God declares himself to be the beginning and the end, which is, and which was, and which is to come, the Almighty.
In Exodus 2:4 the name for God is Lord, Yehovah: the existing one. In Genesis 1:1 the name of God is Elohim. He is mighty rulers. The word is both singular and plural. We see God, the one God existing in the Father, Son, and Holy Spirit, which is three.
In Joshua 3:11 he is Adon which means Lord. In Exodus 6 he is Shaddai, the Almighty. In 2 Kings 20: 5 he declares himself to be Rapha. Our God is Yehovah Rapha or the God in whom healing and restoration exist. God has made himself known as our banner, shepherd, peace, provider, and more.
In Psalms 91 God is identified as Elyon: Most High, Shaddi: Almighty, Yehovah: The Existing One, Machaseh: Shelter, Matsud: Fortress, Eloheem: Rulers, Shield and Covering. In Matthew 1:26 and Isaiah he is Emmanuel and Immanuel: God With Us. In Jeremiah 23:6 he is Yehovah Tsidqenu, The Lord Our Righteousness.
He is ever watching over humans to perform his word in them as they by faith take his provision. We see in 2 Chronicles 16:9 that the eyes of the Lord run to and fro throughout the whole earth, to show himself strong in behalf of them whose heart is perfect (whole) toward him. God is our champion and God is holy. We must recognize that he is altogether right in everything. God is our covenant Friend, Father, and Comforter. The Almighty, the self-existing one who is Love, loves humans.
