I believe that Almighty God loves all of the people on the face of the earth, and wishes that each and every person would love Him too. God is Love, Unconditional Love.
I further believe that Jesus the Son of God, recognized God the Father's desire that man should be able to have a personal relationship with The Father, but since man sinned, it would take the sacrifice of a perfect creation, to erase the sin of man to permit such a personal relationship, as God hates sin.
Therefore Jesus volunteered to be that perfect sinfree sacrifice, permitting Himself to become man, and face the humiliation of being crucified and resurrected, to remove man's sin-debt and at the same time remove spiritual death from man's destiny.
Thus Christianity was started, to establish the one and only pathway for man, who desired to have a personal relationship with God.
Most of the various Christian spin-offs are in a simplistic view, merely branches of the same tree. Those branches that do not bear fruit, are barren and dead are lopped off so that fruit may be produced. Those religions who go against God and His teachings will be uprooted and destroyed.
