We are a work in progress because every day the Holy Spirit will convict us of something of our old self that has to go. From the day that we were born again this has been going on and will continue until we have a Christ like nature. Ever had that feeling when you are in prayer, that the Holy Spirit is trying to tell you something.
He is trying to remove blockages that would stop us from having prayer answered. This will eventually bring us into a full intimacy with our Lord and maker. We have an old nature that will try to fight this. But the spirit of God will never give up, and he will keep on giving us a nudge until we listen.
