This Book encourages you to know that God loves you to know Jesus Christ is your Savior. The Holy Bible makes you an optimist. The leading psychiatrists of the world today have come to recognize the power of optimism as a healing force in the human personality. There isn't a book that gives the basis for optimism like the Bible does because the Bible deals ultimately with your dying. God has told us this.
Major faiths believe it.
They may have differences, if you are a Jew or a Christian or a Muslim, you are all taught there is life beyond death. All religions have their own concepts of heaven and hell. I believe in a God. I believe He came to this earth in Jesus. I believe He died on the cross for us.
