Imagine you get a letter in the mail saying a distant relation has left you 10 million dollars. The letter tells you that the money has been deposited in an account under your name at your local bank and can be withdrawn as soon as the appropriate legal processes are accomplished. For all intents and purposes you're a millionaire! This is your new financial position. However, until the legal paperwork has all been completed and you actually go down to the bank and make a withdrawal, your new financial position makes no difference to your daily condition. Until you actually start spending your newfound millions, the fact that you're a millionaire has no difference upon how you're living. So, too, in the spiritual realm. God has made you a spiritual "millionaire" in Christ. But this doesn't necessarily mean you are actually living like it. Many believers don't have any idea what their spiritual position is in Christ; they don't know that they've been "blessed with all spiritual blessings in heavenly places in Christ Jesus." (Eph. 1:3) And it shows in how they live, in their condition. Although they have been clothed in the righteousness of Christ, they remain in bondage to the "old man," to the impulses of their carnal nature, and to sin. It isn't that they haven't actually been saved; they simply are ignorant and continue to have to resist their "fleshly lusts which war against the soul." (1Pe. 2:11) The Christian life for most people ends up being a process whereby God brings what is true of them in their position in Christ into their daily living, or condition. As that happens, sin becomes less and less the rule and more and more the exception.
Selah.
Using the millionaire anecdote again. Once you know your a millionaire, you'll start wanting to live like the millionaire. Even though your paper work isn't done and you withdraw some money. Anyone with a bit of sense. Would get more information on what it entails to live the way of the millionaire, they will go to places where other millionaires hang out and get to know them.
They aught to go and learn the rules of the millionaires, because they live by different standards than the normal Joe lives.
So, it does make a difference and it does change you lifestyle and how your living.
And it's the same for being Born Again. Once you become Born Again, you will want to know more about Christ, you will want to have your mind renewed, You will read His word and apply it to your life. You will ask God to help you to obey Him and His word. You will go about trying to win the lost. Yes, you'll start off with milk of the word as a small child, but you will grow in the Lord and be able to chew the meat of God's Word and do that He has commanded us to do.
Once your clothed in the righteousness of God, you are no longer "in Bondage" to anything.
Rom 8:15
For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
Rom 8:21
Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
Gal 4:3
Even so we, when we were children, were in bondage under the elements of the world:
Paul even ask, why when you are known by God, why would you go back to those things that put you into bondage.
Gal 4:9
But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage?
Ignorance is no excuse. God has laid out His plan for Man, through His word and in man's Heart. The conscience of man bears witness to what we know that is right or wrong.
