This is a symbol of baptism, which now saves you-- not the putting away of the filth of the flesh, but the answer of a good conscience toward God, through the resurrection of Jesus Christ,
The meaning of this part of the verse, therefore, may be thus expressed: “Noah and his family were saved by water, the antitype to which (to wit, that which in important respects corresponds to that) baptism (not the putting away of the filth of the flesh, or the mere application of material water, but that purifying of the heart of which it is the appropriate emblem) now saves us.”
