Isaiah 45:1 says, Thus saith the Lord to his anointed, to Cyrus, whose right hand I have holden, to subdue nations before him; and I will loose the loins of kings, to open before him the two leaved gates; and the gates shall not be shut; Matthew Henry points out that more is said about Cyrus now, because he was a type or representative of what Jesus Christ would do for people. He also says that there is some question about Cyrus’s origin, but that he soon made himself powerful and famous. Of course, there is no doubt about the origins of Jesus Christ. He is the only begotten Son of God. Isaiah said that God was to open two gates before Cyrus who was referred to as His anointed, and they would not be shut. When God opens a door for us, nothing can ever shut it. God was going to give Cyrus victory over more than one kingdom, but He wouldn’t start with Babylon. That would come later.
Verse two adds, I will go before thee, and make the crooked places straight: I will break in pieces the gates of brass, and cut in sunder the bars of iron: God said He was going before Cyrus, and the first thing he said He was going to does make the crooked places straight. This is the first thing that happens when people hear the gospel and accept Jesus Christ as their Savior and Lord. Then, just as God broke down all the gates that stood between Cyrus and victory, He will break down all strongholds that stand between Himself and us. Cyrus would not have to break them down, but God would open them for Him. We as Christians don't have to break down doors of opposition but only have to share the gospel, then God will work to convict the ones to whom we witness to accept His gift of salvation.
Verse three continues, And I will give thee the treasures of darkness, and hidden riches of secret places, that thou mayest know that I, the Lord, which call thee by thy name, am the God of Israel. God said He would give Cyrus the riches hidden in these kingdoms so that he would know that God was God. God gives us the spiritual riches of His kingdom when we accept Jesus Crist as our personal Savior and Lord. Until we accept Him, these things will always be hidden to from us, and we will never receive them by our own merit. They are a gift from God, and we need to give Him the praise for them.
Verse four states, For Jacob my servant's sake, and Israel mine elect, I have even called thee by thy name: I have surnamed thee, though thou hast not known me. God said He was going to work through Cyrus for the sake of the descendants of Jacob and Isreal, even though Cyrus had not known God. He was not born into the kingdom of Israel but was still going to be used by God to achieve His purpose. Until we accept Jesus Christ as our Savior and Lord, we do not really know God. It doesn’t matter what family we were born into or weren’t born into. Christianity is not based on nationalism and being a believer in God really wasn’t in the Old Testament either. The people of Israel weren’t special because they were somehow morally superior to others because of being born to the family of Abraham. They were special because God called them into a relationship with Himself so He could work through them to reach the whole world. The same is true of Christians today.
