No, it is not a necessity. It is simply stealing. Although some may attempt to justify shoplifting for those who are in need, it does not change the fact that it is just stealing. Take a look at what it says at Ephesians 4:28 "Let the stealer steal no more, but rather let him do hard work, doing with his hands what is good work.” Also take a look at one of the original 10 commandments at Exodus 20:15 "You must not steal.”
Those who are dedicated to stealing put themselves at great risk. Look at what you can lose. It's mentioned at 1 Corinthians 6:10 "thieves, greedy people, drunkards, revilers, and extortioners will not inherit God’s Kingdom." Those who do not inherit God's Kingdom do not get everlasting life. Those who DO want everlasting life stay away from stealing.
