(Verse 10) - He who is bathed refers to those who are redeemed and have been washed clean by the application of the blood of Christ. Actually, they are made clean by the imputation of their sin to Christ on the Cross. The shedding of blood there was the payment of the ransom price to God in order that He might be fully satisfied with regard to the sin of those for whom Christ died. This is the bathing that is in view. Once one has been so bathed, one is fully clean. God is completely satisfied and no more satisfaction need be made. There is little wonder that Jesus will tell Peter what He tells him.

He who is bathed needs only... is noteworthy. There is still need in the life of one who has been bathed. The bathing satisfies with regard to eternal destiny but does not eliminate the need for all types future cleansing. He is clean in the ultimate sense, but there is still the ongoing need for some form of cleansing. Only speaks of the truth that the cleansing needed is of a lesser degree than that called bathing. It is of the same general type but of a lesser degree.

To wash his feet speaks of the same degree of cleansing as needs only did. There is no need for bathing the whole body all over again; only the need to wash the dust of the journey from off of the feet. But is a contrastive that sets the effect of bathing against the effect of washing the feet. It is as if the washing of the feet is complimentary to the bathing of the whole body, restoring the body to its previous state of cleanness.

Is completely clean refers to the effect of the bathing and suggests one of two things. Either the complete cleanness persists in spite of the dirty feet or the washing of the dirty feet is all that is necessary to restore the state of complete cleanness. In the first instance the dirt of the feet has no real effect on the clearness spoken of but is regarded as merely cosmetic and of no true, abiding significance. The disciple is truly clean and the matter of dirt on his feet does not affect that fundamental cleanness. In the second instance, the dirt on the feet does affect the cleanness but only in a limited fashion and does not make the whole body unclean but only the feet themselves. As we will see in a moment, the first option seems to fit the best with what we know of what this represents.

And you are clean supports this assertion. Peter was clean in spite of the dirty feet. Peter's need was not for total cleansing, but only to bring his feet into a state consistent with the rest of his body. His dirty feet did not under his entire body deity.

But not all of you further supports the idea that that Peter's dirty feet didn't ruin the fundamentally clean state he was in. Jesus contrasts him with Judas (see the next verse) who was not bathed and whose feet, clean or not, made nothing different.

How do those facts apply to my life?:

 Of course. this passage speaks of forgiveness. The bathing is the cleansing that comes at salvation. That cleansing is complete and accomplished once and for all. Once one is bathed (forgiven or redeemed) one need never be bathed again. However, that does not mean our "feet" don't get dirty. We commit sin and we need to seek God by means of confession to be cleansed from that sin. Peter was redeemed. He did not need to be redeemed again. Judas was not redeemed. Foot washing (the minor cleansing from the sin that results from our walk) was of benefit to Peter as He was already clean. It was of no benefit to Judas as he had never been bathed to begin with.
