If you look up repentance in a Webster’s 1828 Dictionary (the fifth “standard work”):
2. In theology, the pain, regret or affliction which a person feels on account of his past conduct, because it exposes him to punishment. This sorrow proceeding merely from the fear of punishment, is called legal repentance, as being excited by the terrors of legal penalties, and it may exist without an amendment of life.
3. Real penitence; sorrow or deep contrition for sin, as an offense and dishonor to God, a violation of his holy law, and the basest ingratitude towards a Being of infinite benevolence. This is called evangelical repentance, and is accompanied and followed by amendment of life.
Repentance is a change of mind, or a conversion from sin to God.
Let’s define evangelical:
1. According to the gospel; consonant to the doctrines and precepts of the gospel, published by Christ and his apostles; as evangelical righteousness, obedience or piety.
Seriously, I don’t know how any Latter-day Saint gets by without the Webster’s 1828 Dictionary. It’s rare that I ever open the scriptures and not refer to it at least once.
