Flesh & Spirit

Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Ephesians 6:11-13(NKJV)

At times it becomes easy to forget that we are spiritual beings and not merely this temporary flesh. Our flesh and bodies will eventually be gone, but our spirits are eternal and will last forever. On top of that we are continually in a battle, but it's a battle that exists on a spiritual level and not a physical one. Ephesians 6 talks about putting on the full armor of God in order to fight these spiritual battles. However, it is not very clear how we do this on a daily basis. I have heard a number of different views on how this works, but i'm not convinced that any of them are that accurate or correct. So how do you put on "the whole armor of God"?
