ANSWER: We believe none can answer this question fully! There is neither human knowledge, time, nor space that would permit it. Though we may know some things about Him, we can never fully comprehend such concepts as limitless, eternal, and infinite concerning His being and will.
Some attributes of God often ascribed to Him are: self-existent, unchangeable, infinite knowledge, total independence, all-powerful, all-present, righteous, holy, and good. Toward us as sinners, He is full of mercy, “not willing that any should perish, but that all should come to repentance” (II Peter 3:9). In I John 4:8, we are told that He is love! One of the most beautiful pictures of God in the Bible is found in Luke 15:11-32. Here we see our God lovingly concerned about His children and willing to forgive to the uttermost. However, we also see Him described as a God of goodness and severity; goodness toward those who continue in Him, but severity toward the disobedient.
He will one day judge each of us by Christ (Acts 17:31) according to our deeds (Revelation 20:12). The nearest one can come to knowing God is through a deep, thoughtful study of His Word. This we recommend to you!
