Oppression, in a Christian context, does not mean covering sin, or bearing the consequences of another's sin "till death do us part." That, in fact, would not be loving--if this life is his only opportunity for repentance and eternal life. Responding to oppression means resisting in a way that exposes and addresses sin. It means praying and living against one's own tendencies or desire to be a savior and turning to the Savior.
Where sin is involved, we should not be surprised but, instead, should expect the following responses. It is only by God's grace and the knowledge of Jesus Christ that we run to Him when we sin.
