The spiritual freedom of any human is the goal of the Christian doctrine.The Lord Jesus taught people to gain blessed life..
"You shall know the truth and the truth shall make you free. (John 8: 32)"
So, the main aim of Jesus's teachings, is to make a person the owner of the truth and make him free by this way. We can see, that there are two key concepts in the words of Jesus: Truth and Freedom. Any human that needs Freedom, should possess the Truth.
What is Freedom? There is a wide range of addictions, from which a person may suffer, and I think, that if a man is not free, it's no reason to explain it to him. A person can be linked to obsessive desires, habits, insecurity, dependences, fear, fear of death.
A person can find himself in varying degrees of enslavement; namely, it is possible to feel the inner lack of freedom and resist it, and can, being completely weakened, start doing things compelled by addiction.
Let's take a specific example, relevant for many countries - drunkenness. A person can be in the state of compulsion, knowing that he should not drink; and may have been tired to fight, and get drunk. But what is important, that in both cases the same person is in the state of inner lack of freedom. Drunkenness - one of the most widespread manifestations of the lack of freedom, but people can suffer from many other things.
So, what does the Christian doctrine offers a person? No, it does not set up the doctrine to endure hard, though, the people understand that they have no force to reject. If that Jesus taught, He would have said nothing new in comparison with the quarrelsome wife, who continually reproaches her husband. He knows that it is not good, but he can do nothing.
Christian teaching gives inner liberation, or, in other words, the Lord Jesus heals the inner essence of a human, thus making him free.
I think many people realize that only such solution is acceptable; and, therefore, the second question raises: what kind of truth is at stake?
You just need to realize and accept the essence of Christian doctrine. This site, basically, contains such materials. But I'd like the reader should realize it as soon as possible.
Therefore, now I shall express the most basic: the essence of it lies in the fact that Jesus is alive, just like 2000 years before the crucifixion, when He healed and liberated people. And now, even more so, not being burdened by the power of death, He can be nearby anyone who calls on the God. And it is possible for the reason that He was raised; He came to life after death, and He is alive forever:
"Therefore he is able to save people coming to God by Him, since He always lives to make intercession for them. (by Heb. 7, 25)"
So, what to do?
A person should believe that Jesus - the Son of the Mighty God is alive; and should cry to Him for Help!
Then he should experience the power of the mighty God and let Him lead him threw his life. The God leads us threw His Word – the Holy Scripture and His Holy Spirit.
Be blessed by the Mighty God in the name of Jesus!
