To Be Baptized Unworthily

[Bernard Gui]

Mormon 9:29 See that ye are not baptized unworthily; see that ye partake not of the sacrament of Christ unworthily; but see that ye do all things in worthiness, and do it in the name of Jesus Christ, the Son of the living God; and if ye do this, and endure to the end, ye will in nowise be cast out.

How do you interpret Mormon's commandment not to be baptized unworthily? Don't we become worthy by being baptized? Does he mean not to be baptized without understanding and accepting the covenants? Are we sometimes too hasty in getting investigators into the font before they are prepared, or do we need to redouble our efforts to retain them after baptism?
