That when God indwells the believer there is no change?
Absolutely there is a change. But it's not an automatic change in how a person lives, but a change from a dead spirit to a living spirit.
Is God ineffective?
Absolutely not. It is guaranted that at the very moment you believe in the substitutionary death and shed blood of Jesus Christ, the Lamb of God as the payment for your sin the Holy Spirit IS going to make alive your dead spirit. It is an absolute.
He is 100% effective. The issue is we have to know what He is doing.
Why would God indwell a person if there was going to be no change? What would be the point?
A couple of great questions. God indwells a person through His Spirit so that the person is capable of learning and growning and doing the works that God has intended for them to do. Without the Holy Spirit we could do none of those things.
However, it is not an absolute guarantee that the person is going to want to learn, want to grow or allow the Spirit to work through their bodies to do the things that God has intended for them to do.
We sometime forget that when folks are saved they are babies. Amy I don't know if you are a parent or not, but I have two small children and they were not brought into this world knowing how to do the right thing, nor desiring to do the right thing. Those things are learned not automatic.
Baby Christians are the same way. They must be taught to walk in the Spirit and what that means. They must be encouraged to do the right thing. They must be taught that God demands obedience and faithfulness, and that those things are possible, but they are not automatic.
If obedience and faithfulness and good works and a changed life were absolute guarantees then again there would be no need to commmand or demand those things would there?
Why are we told not to grieve or quench the Holy Spirit if a changed life is automatic and those are not things that we would do?
