Simeon, an old man, saw baby Jesus and said in Matthew 2:29-30 (NIV)
"Sovereign Lord, as you have promised, you now dismiss your servant in peace. For my eyes have seen your salvation."
In other words - "Lord, I have waited my entire life for the Messiah. You promised he'd come... but it was a long wait. Now I can die. I have seen your salvation with my eyes."
There's a song called "Hold My Heart" sung by Tenth Avenue North, that describes the agonizing wait for God to act.
How long must I pray, must I pray to You?
How long must I wait, must I wait for You?
How long 'til I see Your face,
see You shining through?
I'm on my knees,
begging You to notice me.
I'm on my knees,
Father will You turn to me?
Jesus has come into the world. Salvation has come. His comfort is near.
As the song concludes:
If You're everything You say You are
Would You come close and hold my heart
