There are those who are constantly at church because they are uncomfortable outside her walls. Then there are those who are a fixture because they are so thirsty for the presence of God. Simeon was the latter. He was a righteous and devout man. And he yearned for the coming of his Savior.
The Holy Spirit had revealed to Simeon that he would not die before he met the Messiah. You could not visit the temple without seeing Simeon and the prophetess, Anna. They spoke with yearning of the coming of the Messiah. When would he come? What would he be like? How would they know it was him? And they prayed. They earnestly prayed for his coming.
