“The law is only a shadow of the good things that are coming—not the realities themselves. For this reason it can never, by the same sacrifices repeated endlessly year after year, make perfect those who draw near to worship.” -Hebrews 10:1
Imagine if you will being an Israelite in slavery in Egypt, and the joy you would feel when finally, after ten plagues and a hike through the red sea, you are free. I don't know that there is a greater parallel for the redemption Jesus bought us than being released from slavery. I sometimes naively feel jealous of people who've experienced both slavery and freedom, and can grasp the greatness of God's gift to us. I was baptised as a a baby, born into the freedom of Christ from the earliest age. It seems non-dramatic to me, but from a big picture perspective my baptism is something that God has been building up to for millennia. The same is true for you. All the trials of Israel, the judges, the law, the captivities and the victories are part of the same story you find yourself in today.
God has written you into an amazing story. The grace you know was prophesied in the old testament. The Bible you read was maintained and protected by countless people of centuries. May you understand and appreciate the privilege that it is to live in this time, when prophecies stand fulfilled and the the Word of God goes out into all corners of the world.
