The book of Revelation can be a bit intimidating to read through and certainly a bit confusing. The book of Revelation can tend to feel like a judgement and cruel on the part of God. While Revelation is indeed a judgement, it's only a judgement for those who haven't chosen to accept the free gift of salvation from Christ. Christ doesn't want to judge anyone, God's will is that if anyone would come to Him, He would save them from judgement. He forgive them of their sins and call them son or daughter.
