 The Holy Spirit is a person that Simeon was very much in touch with, and he wanted to see God's promise of the Messiah in his life. And God, in fact, promised him that he would not die before he saw the Messiah in the flesh. And that's why he was at the temple that day. The Spirit told him to go to the temple that day. He was obedient to what God was saying. Again, may that be said of us as well, that we're sensitive to those callings of God.
