Had a thought about children being baptized before believing. Babies were circumcised without knowing the spiritual meaning, and later they were given the understanding of what it entailed.
So even though some babies are sprinkled today and do not understand why, usually they go through confirmation in their later years and given the meaning of what they went through. Is not that the same thing?
For me, I was baptized about 10 or so in water, but even then the depth of my identity with Christ was not clear. Later in life, when I understood it better, I prayed about redoing it. But, it was like God was saying to me, "I always meet people where they are - I met you at the place of your understanding then - and every time you "die to self" and surrender more of yourself to me, you are acting out what took place years ago."
So, now I feel different about age. And I agree that it is not a requirement for salvation.
