The book of Revelation has both fascinated and intimidated its readers for centuries and rightfully so, yet the name itself would indicate that God wants us to have an understanding of it; for you see the word revelation means “an unveiling”.
“Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near.” Revelation 1:3.
“Jude, a servant of Jesus Christ, and brother of James, to those who are called, sanctified by God the Father, and preserved in Jesus Christ: Mercy, peace, and love be multiplied to you. Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into licentiousness and deny the only Lord God and our Lord Jesus Christ.” Jude 1-4.
“But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe. And the angels [fallen angels, the, “sons of God” who may have had sex with women in Genesis 6: 1-4] who did not keep their proper domain, but left their own habitation, He has reserved in everlasting chains under darkness for the judgment of the great day; as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.” Jude 5-7.
Jude the last book of the Bible before Revelation was written circa 70 to 80 A.D. The author Jude, being the brother of James, thus identifies himself as being the Lord Jesus’ half brother (Judas in Mark 6:3 and Matthew 13:55), there are 4 half brothers mentioned.
“Is this not the carpenter [Jesus], the Son of Mary, and brother of James, Joses, Judas, and Simon? And are not His sisters here with us? And they were offended at Him.” Mark 6:3.
“And again He began to teach by the sea. And a great multitude was gathered to Him, so that He got into a boat and sat in it on the sea; and the whole multitude was on the land facing the sea. Then He taught them many things by parables, and said to them in His teaching: ‘Listen! Behold, a sower went out to sow. And it happened, as he sowed, that some seed fell by the wayside; and the birds of the air came and devoured it. Some fell on stony ground, where it did not have much earth; and immediately it sprang up because it had no depth of earth. But when the sun was up it was scorched, and because it had no root it withered away. And some seed fell among thorns; and the thorns grew up and choked it, and it yielded no crop. But other seed fell on good ground and yielded crop that sprang up, increased and produced: some thirtyfold, some sixty, and some a hundred.’ And He said to them, ‘He who has ears to hear, let him hear!’” Mark 4:1-9.
“Now these are the ones sown among thorns; they are the ones who hear the word, and the cares of this world, the deceitfulness of riches, and the desires for other things entering in choke the word, and it becomes unfruitful.” Mark 4:18-19.
