Ruth was the center piece of Shavuot, also known as Pentecost. The entire book was read at the festival in keeping with the theme of harvest time. Passover came at the barley harvest and Shavuot came with the wheat harvest.
Ruth is important as well because she was the mother of King David (great-grandmother, but you get the idea). For us Christians, she is also the mother of Jesus.
It is no accident that Ruth is so closely associated with the harvest. It is a part of God’s plan to prepare us for the final harvest of people. It is no accident that Jesus was killed at Passover and that the Church was given birth on Shavuot.
I think we often overuse the word salvation. It is the correct term, but we sometimes try to make it carry too much meaning. Our salvation is a gift from God. He gives it to us because he is a God of Mercy. Not one of us has done anything to deserve that gift. Mercy came to us in the human form of the man named Yeshua bar Yosef.
Jesus lived a very human life for about thirty years until God called him to be a prophet to His Chosen Ones, to Israel. Jesus became a living parable of how to be a true son of God until God told him that he had to take on Satan in a no holds barred smack down—and he had to do it after he died a tortures death.
My salvation is neither cheap nor easy, but I have not had to pay the price. It is like a no limit credit card that I do not have to pay back.
But there is a price, of sorts. God asks me to accept his gift.
At first, the simplicity is overwhelming. It can’t be that simple. But it is, and it is not. By accepting the gift I now owe God a favor which I can pay off by being as close to Him as possible. God wants me to return to the perfect life He planned for me. I cannot do that in this world, but I can practice for the next world. I can try my best to do what He wants me to do, even as I fail too often.
Be righteous and do good.
