“Then Jeshua the son of Jozadak and his brethren the priests, and Zerubbabel the son of Shealtiel and his brethren, arose and built the altar of the God of Israel, to offer burnt offerings on it, as it is written in the Law of Moses the man of God.”
Central to returning to the Lord, was the Altar. With it, sacrifices could be offered in accordance with the Law of God. Without it, man would still be striving on his own, attempting to build his way to God. The altar, tragically, involved the sacrifice of the innocent in place of the guilty. This method of atonement was offensive to some; not because of the death of the innocent, but because of the declaration that those offering the sacrifice are guilty.
Long ago, the Cross replaced the altar as the means by which man could access God. The method changed, but the statement it makes remains the same. Man is guilty before God and sacrifice must be made on his behalf. Jesus, Himself, became the sacrifice for us. His blood was shed on our behalf so every guilty sinner might have access to God through Him. Rather than being offended by the fact that you are called a sinner, why not accept the pardon He provides. After all, if you don’t think you are a sinner, you are the only one who believes that.
