Christian is holding in his hand the Word of God.  He has read there that he has sinned against God and must flee from the City of Destruction where he lives if he wants to escape from the wrath to come.

He remembers the sins of his past life and the thought fills him with alarm and dismay.  His sins weigh heavily upon him, like a burden on his back.  His clothes seem to hang on him like filthy rags.  He wants to get rid of his burden but does not know how to.  He cries out in despair "What shall I do?"  He dare not live as before lest he perish in his sins.

Mercifully God will help those that seek Him.

Psalm 38:5  Romans 3:20
