Nothing can be made, and nothing can remain, without the will of God making it and maintaining it. In his love God created angels and men. He made them good like himself, and he intended them for that perfect happiness which he has, and which can come only through likeness to him. The angels are spirits who worship and serve God in heaven. They fulfill his commandments, and are the agents of his will towards this world and mankind.
Human beings are of a twofold nature, both spiritual and bodily.
God has given to angels and men, alone of his creatures, the power of choosing to obey his will or of choosing to disobey. All things else are as God wills them to be, and therefore fulfil the purpose he had in making them. We believe that before mankind was created, evil was already present in the spiritual world. Some of the angels, though created good, and capable of attaining to perfect and permanent holiness, had changed, we do not know how or why, and became evil, rebelling against God. It was Satan who brought evil into the world, and won the consent of mankind to sin, by which the world and mankind were spoiled.
