Johann Heinrich Fussli Satan and Death with Sin Intervening
Sin is the real human trouble: it is the root from which all other troubles spring. Sometimes the trouble is our own sin, but that is not the only trouble of sin. We are also hurt when we suffer from the sin of others. And even if someone were to somehow avoid their own sin and the sin of others, there is the constant of effect of in sin in this world: death, disease, disaster. While the particular ill may be sin in some particular branch, the root will always be sin and the solution will always ultimately found in the grace of God in Jesus Christ.
