And there came a writing to him from Elijah the prophet, saying, “Thus saith the LORD God of David thy father, Because thou hast not walked in the ways of Jehoshaphat thy father, nor in the ways of Asa king of Judah, but hast walked in the way of the kings of Israel, and hast made Judah and the inhabitants of Jerusalem to go a whoring, like to the whoredoms of the house of Ahab, and also hast slain thy brethren of thy father’s house, which were better than thyself: Behold, with a great plague will the LORD smite thy people, and thy children, and thy wives, and all thy goods: and thou shalt have great sickness by disease of thy bowels, until thy bowels fall out by reason of the sickness day by day. 2 Chronicles 21:12-15
Asa was a king of Judah who did right in the eyes of the LORD, but his life ended as being a selfish tyrant. His son Jehoshaphat also had done right in the eyes of the LORD though he aligned himself with Ahab, the evil king of the northern kingdom of Israel. Then along comes Jehoram, and he does wickedness in the eyes of the LORD.
The letter is from Elijah who is the prophet who warned Ahab of his wicked ways, challenged the prophets of Baal on Mount Carmel, and ended their lives with their heads being removed.
Why would Elijah send a letter to the king of Judah? Probably because he had a word from the LORD for Jehoram to know his plight and the tragedy coming on his family and himself. Jehoram was going to die a horrible death because of his sin and the evil of his heart.
Death is the result of sin. Sin came into the world by the first man, Adam. Because Adam sinned, every one who has been born into this world is a sinner there is no escaping sin. There is, however, One who was born of woman who never sinned. His name is Jesus the Christ, Son of the Living God.
Jesus, being sinless, without any guilt, shame or remorse died on the cross becoming sin for us (2 Corinthians 5:21), being buried, and rising again from the grave alive forever more. Sin, death, Hell and the grave are defeated, and hold no power over those who come to God through Jesus Christ. In Jesus we have everlasting, that is eternal life.
