Several comments allude to the fact that the devil, Satan, has been defeated. Is that past tense or present tense? Revelation 12:7-9, says Satan and his angels were cast to this earth. If present tense do we still sin? If so why? Many of us are seeking rational explanations. We were born into sin, our sins are only little ones, we will make changes later. It has been a fact for a couple of thousand years, Satan has been defeated. My solace is, Jesus has saved us from our sins. Not in spite of our sins.
