The whole Word, even when it is actual history, is a parable or metaphor teaching us about our personal spiritual growth and development. Jesus Christ is the physical manifestation of the One God, called Jehovah in the Old Testament. The Christian idea of the trinity divides the Godhead into three persons. God is one. We are resuscitated on the third day after death and live on as males and females in the Spiritual World.
Marriages can last to eternity.
Heaven and Hell are both states of mind in which we can be while here on earth. Whichever path we choose is how we live on after death forever. No one's sins are washed away by baptism. It is a sign that a person may be reborn spiritually if he or she puts away evils in life and lives well. God's greatest desire is to preserve our freedom.
