The Bible uses many terms to describe Christians. They are called Christians, children, children of God, children of light, children of the day, children of obedience, believers, friends, brothers, sheep, saints, soldiers, witnesses, stewards, fellow citizens, lights in the world, elect of God, ambassadors, ministers, servants, disciples, heirs, joint-heirs, branches, members of the body, living stones, epistles, temples, beloved, followers, overcomers, victors, conquerors, and so forth. All of these terms are loaded with meaning, so it would take a composite of all of them to define what a Christian really is.
