A Confirmation is a confession of one's faith. A faith that was given to them by the Spirit. It is also a understanding that our learning of Christ is never ending and that we live in continued catechises for our entire lives in this world.
My daughter became a Christian by hearing the word of God. My daughter became a child of God at her baptism when she was only 11 days old. She was baptised with plain water, "from the tap" to use her words. This water was then combined with God's word and she became holy and set apart from all people.
During her questioning which was before our pastor, family and one set of friends she spoke of the faith that was given to her by God. In a very poised manner, she told us of the triune God, her sinful nature and her need of a Savior. She spoke of the Commandments, Creed, the Lord's prayer, Absolution, Baptism and Communion. She was alone and the only confirmand and she did a beautiful job.
In the Sermon our Pastor did a beautiful job of telling Chick #1 that Christ was coming and where he would be. He would be placed into her mouth under the bread and wine of communion for the forgiveness of her sins.
Here is the whole family.
