Because Kari said it so well, please go read her thoughts here.
Our homestretch is a long time away. We may never see an empty nest, but I don't regret the choices we've made. One day at a time, one blessing (and trial) at a time, God has provided, and He has promised to continue to do so. I have no fear of the future. Last night I was lying in bed thinking of the last lines of an old Sunday School chorus we used to sing, "For if the Father's eye is on the sparrow, then surely he will care for you. He knoweth, and careth, each burden, he beareth. For if the Father's eye is on the sparrow, then surely he will care for you."
That led my thoughts to a hymn that we sing in our church services now, which also has a line about God caring for the sparrow. You can read and listen to it here: His Eye is on the Sparrow.
Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father. Fear ye not therefore, ye are of more value than many sparrows. Matthew 10:29, 31
The sparrows. The children. And us. Fear ye not.
