God did not make any devils. He made angels in quite a sinless condition, but also free, even as man. By misuse of their freedom of choice, some angels turned themselves into evil spirits. In his evil will Satan then tempted man. God permitted this, for man had to prove the reality of his devotedness to God. Anybody can serve God if he is never tempted. Man’s real glory is to be tempted to abandon God, yet not to consent.
