[1]: John 1:7 teaches us that the cleansing of one's sin is done through walking through his path.

But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.

[2]: Isaia, 58:5 teaches us that true penance is required.

Is this the kind of fast I have chosen, only a day for people to humble themselves?
