The Aseity (Self-Existence) of God
"The Father hath life in himself." - John 5:26
“The God who made the world and all things in it, since He is Lord of heaven and earth, does not dwell in temples made with hands;25 neither is He served by human hands, as though He needed anything, since He Himself gives to all life and breath and all things." (Acts 17:24, 25)
"Before the mountains were born or You gave birth to the earth and the world, even from everlasting to everlasting, You are God." (Psalm 90:2)
"God is self-existent and independent. He has all life, glory, and blessedness, in and of himself. His existence is necessary and underived; for his name is, 'I am that I am.' - Exod. iii. 14. His glory and blessedness are likewise underived. His glory necessarily results from, or rather consists in, the absolute perfection of has own nature, and his blessedness is all summed up in the possession and enjoyment of his own infinite excellencies. Being thus all-sufficient in and unto himself, he must be independent of any other being. He stands not in need of any creatures which he has made, nor can he derive any glory from them. Every other being receives its all from him, but he receives no advantage from any. 'For his pleasure all things are and were created; but none can be profitable to God, as he that is wise may be profitable to himself; nor is it any gain to him that they make their ways perfect.'—Rev. it. 11; Job xxii. 2, 3." - Robert Shaw
