The answer involves looking into God's word the Bible, finding help to understand truth about Bible teachings, and true Christianity, answering questions such as is the soul immortal, what's involved for those receiving the privilege of heavenly life, and what is God's purpose for the earth--can people live on a cleansed earth in Paradise endlessly?
From God's word we can receive loving guidance and wisdom from God for right living with a joyful heart, looking forward to the rulership of God's Kingdom.
