Emotion

One can experience an emotion or feeling without it properly being an affection, but one can rarely if ever experience an affection without it being emotional and involving intense feelings that awaken and move and stir the body.

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards Religious Affections,
p. 45

Affections

God has so united the material (body) and immaterial (soul) aspects of our being that it is virtually impossible for the latter to be greatly moved and it not affect the former.

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards' Religious Affections,
p. 44

Joy

This is a joy shot through and through with the resplendent majesty of the beauty of God's being. It is not fleshly or worldly joy, nor the joy that comes from earthly achievements or money or fame. It is a joy that has been baptized, as it were, in the glory of God himself.

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards' Religious Affections,
p. 40

Trials & Pains

"Perhaps most important of all is that trials and pains purify and increase true spirituality. They not only enable us to see and discern what is true from what is false, but also "tend to refine it, and deliver it from those mixtures of that which is false, which encumber and impede it, [so] that noting may be left but that which is true."

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards' Religious Affections,
p. 37

Revival

...the religious intensity of 1741 could not long be maintained. The dreadful concerns, the traumatic awakenings, the accelerated devotion - these by their nature are of limited duration. The fever pitch must soon pass, else the patient dies... The ebb of this flood of revivalism would seem then to require no elaborate explanation: it declined simply because it had to, because society could not maintain itself in so great a disequilibrium.

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards' Religious Affections, p. 31. quoted from Gaustad, Great Awakening in New England, p. 79

Conversion

It was very wonderful to see how person's affections were sometimes moved - when God did as it were suddenly open their eyes, and let into their minds a sense of the greatness of his grace, the fullness of their hearts as it were to leap, so that they have been ready to break forth into laughter, tears often at the same time issuing like a flood, and intermingling a loud weeping. Sometimes they have not been able to forbear crying out with a loud voice, expressing their great admiration.

Sam Storms, Signs of the Spirit: An Interpretation of Jonathan Edwards' Religious Affections, p.26

Repentance

One can experience the deepest possible remorse over sin and not repent. Both Esau and Judas demonstrate this. Indeed, we must all learn to distinquish between the sorrow that comes from being caught and the sorrow that comes from a deep, inward hatred of sin and longing for the glory of God that is the distinquishing feature of a regenerate person.

Richard Owens Roberts, Repentance: The First Word of the Gospel p. 86.
