What sin? As far as I'm concerned if Jesus could forgive and forget my sins, then so can I. When God looks at me he doesn't see sin, but Jesus' righteousness that he gave me. As for dwelling in us fully, why not? Sin isn't the issues it is unbelief. people don't go to hell for sin, sin has been forgiven. They go to hell because of unbelief. They do not believe that Jesus has paid their price. Similarly, we cannot receive the fulness of God not because of sin, but because we do not believe that we can.
Ephesians 3:19 "And to know the love of Christ, which passeth knowledge,that ye may be filled with all the fulness of God."
Simply put, the Bible says we can.
So, in your opinion, if it's not due to sin, but unbelief, then a person who simply "believes" they can contain the fullness of God, through Christ, then, right?
I believe in order to be a fit container for all of the Holiness of God, belief and true repentance from sins would involved to contain the fullness of God, and become like God/Christ...
I don't believe a person can be "like God" and still be sinning, are you saying that just simply by belief alone, (and one can still be sinning) one can be "Like God"? just by simply believing it?
If we can contain the fullness of God (and still be sinning) simply by believing, then why don't we have more "little Christ's" out there? moving mountains, performing miracles, signs and wonders, turning water to blood, calling down fire from heaven, teaching advanced knowledge about God, that sort of thing?
You "believe", have you ever been extremely tempted beyond measure to try and perform the miraculous, but were to afraid to try it out? I once was tempted strongly to try and raise somebody up from the dead, but while, I felt the power was there, and I had the faith and the strong belief and conviction that it could be done through Jesus Christ through me, but, by the time I got there they had already took the body, but I was fully convinced 100% without a doubt that it could have been done (at that particular time) but I didn't get to "try it out" as they had already taken the body, but I was convinced of this, regardless of my sin, working on faith alone...
Just thought I'd share that,
God Bless!
