God is a personal being and not just some nebulous force. He is one being yet is manifested in three personalities – the Father, the Son, and the Holy Spirit. He is self-existent, immutable [unchanging], infinite, outside of time [eternal], omnipresent [present everywhere], omnipotent [all powerful],  omniscient [all knowing]. There is no evil in Him. God is the Creator, Sustainer, Savior and Judge of everything.

Self-existance means that God was in existance before everything that was made. He is not a created being. He is self-sustaining and is in existence forever.

He is immutable, which means He is unchanging. He is the same yesterday, today and tomrrow. The God of the Old Testament era is the same God in the New Testament and is the same today.

He is infinte, eternal, existing outside of time.

His omnipresence means He is everywhere at the same time. His omnipotence speaks to Him having all power, all power / energy resides and eminates from Him. Omniscence describes the fact that He knows everything – He cannot learn because He already knows it all.

There is no evil in Him because He defines goodness. If some thing contradicts His nature then by definition that thing is evil.
