Devil vs. Demon
King James Bible
The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter.

Then He said to her, "For this saying go your way; the demon has gone out of your daughter."
Mark 7:26, 29
Word definitions from Webster’s 1828 Edition:
Devil
In Christian theology, an evil spirit or being; a fallen angel, expelled from heaven for rebellion against God; the chief of the apostate angels; the implacable enemy and tempter of the human race.
Demon
A spirit, or immaterial being, holding a middle place between men and the celestial deities of the Pagans. The ancients believed that there were good and evil demons, which had influence over the minds of men, and that these beings carried on an intercourse between men and gods, conveying the addresses of men to the gods, and divine benefits to men. Hence demons became the objects of worship. It was supposed also that human spirits, after their departure from the body became demons, and that the souls of virtuous men, if highly purified, were exalted from demons into gods. The demons of the New Testament were supposed to be spiritual beings which vexed and tormented men. And in general, the word, in modern use, signifies an evil spirit or genius, which influences the conduct or directs the fortunes of mankind.

For John came to you in the way of righteousness, and you did not believe him; but tax collectors and harlots believed him; and when you saw it, you did not afterward relent and believe him.

In theology, to sorrow or be pained for sin, as a violation of God's holy law, a dishonor to his character and government, and the foulest ingratitude to a Being of infinite benevolence.

Servant vs. Slave
King James Bible
But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
Romans 6:22
For he that is called in the Lord, being a servant, is the Lord's freeman: likewise also he that is called, being free, is Christ's servant.
1 Corinthians 7:22
New King James Version
But now having been set free from sin, and having become slaves of God, you have your fruit to holiness, and the end, everlasting life.
Romans 6:22
For he who is called in the Lord while a slave is the Lord's freedman. Likewise he who is called while free is Christ's slave.
1 Corinthians 7:22
Word definitions from Webster’s 1828 Edition:
Servant
A person, male or female, that attends another for the purpose of performing menial offices for him, or who is employed by another for such offices or for other labor, and is subject to his command. The word is correlative to master. Servant differs from slave, as the servant's subjection to a master is voluntary, the slave's is not. Every slave is a servant, but every servant is not a slave.
Slave
A person who is wholly subject to the will of another; one who has no will of his own, but whose person and services are wholly under the control of another. In the early state of the world, and to this day among some barbarous nations, prisoners of war are considered and treated as slaves. The slaves of modern times are more generally purchased, like horses and oxen.
In Scripture, a slave; a bondman; one purchased for money, and who was compelled to serve till the year of jubilee; also, one purchased for a term of years.

Isaiah 14: 14 tells of Satan's ultimate counterfeit: ". . . I will BE LIKE the most High."
