What is entire santification?

I find it that once you conquer a certain sin, only then can you tell someone else about it. For example being a cleptomaniac you probably should not be rebuking others for stealing, however once you do stop doing it you can tell others hey, I know what it is I used to steal all the time, I stopped and you need to repent as well.

Jesus said we should first fix ourselves so we can see to fix our brother more clearly.

I don't believe that entire sanctification is possible on this side of heaven, everyone will always have some sort of sins they have to deal with, it may appear they are completely sanctified because maybe their sins are not out in the open.

I just googled that site. It states they are a Christian site that recognizes all Christians are a work in progress, so those Pharisaic perfectionists must be in their glory looking down at everyone.

We don't know about sanctification without caring about the will of God for us and our lives. There is our God-given conscience that shows God's will for us, that we have not deadened with becoming numb to it, and maybe giving in to social pressures with accepting what we here from society or our social environment. The Bible is important to us for that. All of what God says for people to start with is God's will, what is said later in the Bible in place of that is something else, like what God permits, or concession from God, or else you have to conclude that God's mind changes. The things said to start with are God's will for us. Sanctification would have awareness to come to this and to not sin more

We all live for God's Glory not our own.

When any of us live primarily for ourselves we are so likely to go contrary to God and to God's will.

I read that in either last chaper of Galations or first chapter of Eph.

We should then want to live according to God's will, and for that we need to be open, to what we would be shown, from things we have yet missed, in the Bible showing God's perfect will from the start, above concessions with permissions and allowances to people.
