Its easier to repent after the sin you just commited because you just got it out of your system. Jesus Died for us to have enternal life and not to take it for granted. So when do we say no. When do stand as Jesus stood before the devil, mankind, pharisees and last but not least, God. We have free will, but if you give God your will, He will give you the Power to Avoid temptation.
