The Holy Ghost had revealed to Simeon that he wouldn’t see death until he saw the Lord’s Christ. To put it plainly, he was guaranteed a next breath as long as he didn’t see Jesus. 
Some would have fled any place that might have the potential of being visited by Christ just to live a little longer. But Simeon chose not to. He, being led by the Spirit, went to the temple: the very place babies went to be dedicated to the Lord. It was here that Simeon was given the honor of blessing the baby Jesus, his parents and prophesying about the wonders of Christ. 
Simeon understood that running from the presence of Jesus wasn’t worth missing out on the glory of being part of His story. 
I am praying that you and I will have that same frame of mind causing us to be willing to offer everything we have to be used to glorify Christ.
