Sin and relationship with man

Sin is any action or thought that undermines the authority(will) of God in our lives.Satan uses it as a weapon to fight God through His beloved creation (us):we become defenseless to all his attacks,since we lose our righteousness(spiritual clothes) that acts as a protective barrier for us.Overtime we become weak and dead spiritually to even anything connected with us.The end result is failure and death.

God desires us to be holy and righteous before Him in order to glorify His holy name(God's purpose for creation).Satan was chased out of heaven because he wanted to be God,so he wants to level the score by attacking anything dear to God.Sin would steal from us spiritual gifts,life and blessings even though it may appear appealing and it's end is death.
