Of all the creatures God made in the physical world, mankind alone was said to be made in his image and given dominion. Angels are not mentioned at all in the creation account, but appear suddenly, without explanation or specifications, at the Fall of Man. Only much later in the record of revelation are we told they were made to be ministering (sacredly serving) spirits by God. Yet, even though salvation and redemption hold a fascination for them, they have no ability to be redeemed through faith.
Though they are spiritual beings, as is God, many of them fell into rebellion with Satan. Those, at least, had to have had some kind of freewill capacity (see this as to why), although we can only guess as to its nature. We don't know why unfallen angels did not fall, nor indeed, if they even had the capacity to do so in the first place. Regardless, we can be thankful they, at least, are faithful to God and serve the heirs of salvation amongst mankind to this day.
Mankind is a strange word to generically refer to all human beings with, but it is a biblical way of looking at things. Today's feminists may be bothered by designations that seem better suited to males than females, but believers in the Bible recognize that there is nothing inherently wrong with such. Men are made in the image of God and are tasked with dominion--some are male, some are female. There is absolutely no distinction in the image of God that either gender bears nor in the mandate of dominion they were given.
Only sin, followed by the curse and death has affected the relative status of both types of men. Enmity between the sexes exists, because under the curse, females were placed beneath males in the dominion mandate. In the perfection of God's created order before the Fall, male and female had no more significance than reproductive utility. In Christ, post-redemption, after the curse is no more, there is neither male nor female to any spiritual consequence, which will be particularly evident after the Resurrection.
