A Baby Dedication is a ceremony in which believing parents, and sometimes entire families, make a commitment before the Lord to submit a child to God's will and to raise that child according to God's Word and God's ways.
Train up a child in the way he should go; even when he is old he will not depart from it.
Behold, children are a heritage from the Lord, the fruit of the womb a reward.
Christian parents who dedicate a child are making a promise to the Lord to do everything within their power to raise the child in a godly way, prayerfully until he or she can make a decision on his or her own to follow God.
Parents who make this vow of commitment are instructed to raise the child in the ways of God, and not according to their own ways. Some of the responsibilities include teaching and training the child in God's Word, demonstrating an example of godliness, disciplining according to God's ways, and praying earnestly for the child.
When God answered Hannah's prayer by giving her a son, she remembered her vow:
As surely as you live, my lord, I am the woman who stood here beside you praying to the LORD. I prayed for this child, and the LORD has granted me what I asked of him. So now I give him to the LORD. For his whole life he will be given over to the LORD." And he worshiped the LORD there.
You shall love the Lord your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.
Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord.
And they were bringing children to him that he might touch them, and the disciples rebuked them. But when Jesus saw it, he was indignant and said to them, Let the children come to me; do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it. And he took them in his arms and blessed them, laying his hands on them.
Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations.
