Moroni 8:20

And he that saith that little children needeth baptism, denieth the mercies of Christ, and setteth at nought the atonement of him and the power of his redemption.

Anyone who says little children need baptism rejects Christ’s mercy. That person says Christ’s sacrifice and his power to save don’t matter.

“Anyone who says little children need baptism is denying Christ’s mercy, rejecting his sacrifice, and dismissing his power to save.”
