Life here is in preparation for the next world. Satan tries to deceive people by teaching there is no God, or God is dead, or as a loving heavenly Father He lets us do as we please, or there is no heaven or hell and death ends all, or God will save all men at last. The thrust is that God has revealed Himself and holds every person responsible for his actions.
Mr. William MacDonald here shows that we will not have another chance. Each individual has only one lifetime; there is Only One Time Around.
