Let us consider a word... say, "Justification". The basic idea behind it is "just" or righteous, good, correct. If you take "just" and add different ends to it, you get different words. Add an "ly" and you get an adverb. But when you add that "ification" to something - it means being made _____. You know, like a FACTory makes something - same Latin idea. Justification mean being made just.
So, we get that Christ is our Justification. That He is the one who Justifies and is the Justifier (that -if- group of letter is related to making something).
Now... likewise, if we are talking about "Sanctification" we are then talking about how we have been made Holy.
Now, if we have been made holy, are there effects? Sure! But do my actions make me holy?
It's simple folks - the Holy Ghost has called me by the Gospel, enlightened me with His gifts, and sanctified me (oh, it's that -if- again!).
Let God take the credit for things. Really. Including your sanctification and your justification. Just like we confess in the Small Catechism.
