God knows everything, but this does not eliminate man’s responsibility to confess his sins. Failure to do so forfeits God’s practical forgiveness.
Most people view sin as a private or earthy matter. Yet, every sin is against the Lord. In truth, men can sin against the Father, the Son, and the Spirit.
Sin is not something man does by accident. It is something man does or allows based upon an unwillingness to stop an act before it becomes sin.
The Sabbath was a sign between the Lord and Israel, but it also demonstrates a principle that man needs a period set aside to rest.
