Has your knowledge of God been attained by what other people have told you, or have you read what God's Word, the Bible, actually says? Your physical life here on earth is a mere vapor in the scheme of forever. Don't lose out on eternity in Heaven due to ignorance or arrogance. Read the Good News for yourself. Don't accept somebody else's interpretation, no matter how much of an authority figure they appear to be.
Start by reading the Book of Romans (25 pages long) found in the New Testament. You may be amazed at what God's Word has to say to you.
