(2 Peter 1:3-4) His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness. Through these he has given us his very great and precious promises, so that through them you may participate in the divine nature, having escaped the corruption in the world caused by evil desires.
Knowlege of God and the ways of the Lord through the person of Jesus Christ will bring freedom if these promises are inacted by faith. Real belief changes the game really because if you believe God has saved you out of darkness through the blood of Christ and has given you His approval and acceptence and love- if you truly let this soak deep then you are freed!
Jesus said, "You shall know the truth and the truth will set you free"
Truth is the key to unlock dungeons of guilt, fear, self condemnation, and truth can open locks of imprisoning habits and mindsets. When truth is held in one hand, faith turns the key in such a lock and the door is open to freedom.
To be locked in a prison of the mind is often just as unbearable as being in an actual cell. We construct mental jails all the time, we imprison ourselves in unbreakable chains of sin and addiction all the time because we buy a lie that freedom is not possible. Some scriptural promises are easier to turn in faith then others yet if we were to as Christ followers to lay hold of every spiritual reality at its fullest of measure then nothing would hinder us.
What about Condemnation– now if we have received Christ through faith and we are forgiven by His grace we should not cage ourselves back in the prison of the Law. We should not cry out "Woe is me, Woe is me, in a cage that's door is already opened, like some silly trapped bird that thinks it is still confined but has the freedom to fly out. The silly bird will stay in such bondage as long as he truly believes the door is locked when it is really wide open.
What about fear of future unknowns? Well your belief about God's goodness, control, and wisdom will make or break you here- if you believe God is angry and spiteful or stingy with his blessings or that he does not have as good of an idea as you think you do about what is best for you then you will indeed live in paralyzing fear of what has not even happened yet. But if we truly believe Jeremiah 29:11 says "Plans to prosper you and not to harm you, plans to give you a future and a hope"
Lets not say for one moment God has no struggles in your future or a problemless existence this side of heaven, but I think the other unhealthy extreme is to assume there is nothing to look forward to but miseries and hardship and crushing trial after trial. To believe a prosperity problem free theology is dangerous, to believe in a non ending continuim of unbearable suffering is depressing but to believe the truth is liberating.
Jesus said, "The thief comes to steal, kill and destroy, but I have came to give you life and life abudantly"
We know that does not mean "riches, popularity, and no problems" but it does not mean living your life in despair but victory!
Problems come but we can truimph over them in Christ! And we cannot be too quick to just say God will only bless us with spiritual blessings, (Although this is the greater) but God does provide for our basic survival needs, Jesus also said, "Do not worry about your life, what you will eat, what you will drink, and what you will wear"
He sums his sermon on worry up quite wonderfully by saying "Seek first His Kingdom and righteousness and all these things will be added to you"
The promises of God are activated by faith, not misguided presumption or on the other side of the coin not believing it works.
Unbelief is a prison of its own sort. But as Christians we are called to "walk by faith not by sight"
