Luke 2:25-32 NIV
[25] Now there was a man in Jerusalem called Simeon, who was righteous and devout. He was waiting for the consolation of Israel, and the Holy Spirit was on him. [26] It had been revealed to him by the Holy Spirit that he would not die before he had seen the Lord’s Messiah. [27] Moved by the Spirit, he went into the temple courts. When the parents brought in the child Jesus to do for him what the custom of the Law required, [28] Simeon took him in his arms and praised God, saying: [29] “Sovereign Lord, as you have promised, you may now dismiss your servant in peace. [30] For my eyes have seen your salvation, [31] which you have prepared in the sight of all nations: [32] a light for revelation to the Gentiles, and the glory of your people Israel.”

When people met Jesus their lives were in some way made complete – shepherds rejoice, wise men worship; Simeon had waited all his life for this moment and now he is ready to move on “dismiss your servant in peace…”
Where are we on the contentment scale?

When peace like a river, attendeth my way,
When sorrows like sea billows roll
Whatever my lot, thou hast taught me to say
It is well, it is well, with my soul
It is well
With my soul
It is well, it is well with my soul
