Dear  Iacobos.  Strong`s  Exhaustive Concordance Of The Bible   tells us that the origin of Satan is unknown,  that proves to me the well-known fact,:  any place devoid of God`s  Light    =   Darkness.  Satan/Evil  was found somewhere up in heaven,  and found other like-minded  beings,  and God threw out the lot.  The fact is : when the Serpent had found a chance  to talk and lie to Adam and Eve,  ( our proto-types)  they rather believed the lies  of the Serpent/tempter, than  the Love of God.  The Bible tells us how  Adam and Eve were  banished to Earth,  and all Mankind after them.  Instead of repenting,  all Mankind grew farther and farther away from God,  and became more selfish and unloving.  In time Jesus came, and paid the prize we  ( Mankind)  could not pay to God`s Law.  Jesus died that we might live,  He became our Saviour and   reconciled us to God.   Jesus showed us God as God really is: our Heavenly Father who wants us back again.  The Bible told us again and again:  " Repent,"  change from being selfish and unloving:  to Loving God with all our hearts,  with all our souls, and with all our minds.  Also: Love our neighbour:  all others,  friends or not friends, as we love ourselves.  In Matthew,  chapter 22, verses 35-40,  Jesus  tells a Lawyer: "  The first and great Commandment,  also the second Commandment.   God wants our Love,  selfless and freely given,  without conditions asked.  God is Love  and God wants loving children/sons and daughters  to live with Him for eternity.  Jesus our Saviour,   also The Way back to God where we came from,  is waiting to help and lead us back to where we came from.  Heaven/God`s Kingdom  is ALL LOVE,  and only   God our Heavenly Father and all Christian brothers and sisters  will be found there.  There will be none of the empty and shortlived pleasures  you are looking for,  and Satan`s empty promises and lies  will be no temptation  at all,  Satan will have no chance  in Heaven.  We are on Earth to learn to say NO  to all Satan`s  empty promises,  and we will have learned the meaning of selfless Love and Charity.  I say this  with love.  Greetings from Emmy,  sister in Christ.
