If the death of Christ was that which satisfied God for our sins--then there is infinite evil in sin, since it could be not expiated but by an infinite atonement.
Fools make a mock at sin, and there are few who are duly sensible of its evil. But certainly, if God should exact the full penalty of you--your eternal sufferings could not satisfy for the evil there is in one vain thought. You may think it severe, that God should subject His creatures to everlasting sufferings for sin; but when you have well considered that the Being against whom you sin is the infinitely blessed God, and how God dealt with the angels that fell--you will change your mind. "These he has kept in darkness, bound with everlasting chains for judgment on the great Day!" Jude 1:6
Oh the depth of the evil of sin! If ever you wish to see how great and horrible an evil sin is, measure it in your thoughts, either by the infinite holiness and excellency of God, who is wronged by it; or by the infinite sufferings of Christ, who died to atone for it--and then you will have deeper apprehensions of its enormity.
