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,
Not the putting away of the filth of the flesh - Not a mere external washing, however solemnly done. No outward ablution or purifying saves us, but that which pertains to the conscience. This important clause is thrown in to guard the statement from the abuse to which it would otherwise be liable, the supposition that baptism has of itself a purifying and saving power. To guard against this, the apostle expressly declares that he means much more than a mere outward application of water.
