Freedom always comes with a risk. The risk of misusing it. The risk of licentiousness to go uncontrolled in life. No wonder the churches over the ages teaches about freedom in Christ doctrinally, but never encourage people to apply it in practical life. For the practical purpose, they think, that people need law. At least some of them, like the 10 commandments for example. So they 'teach' freedom, but never let them live in freedom.
The result is slavery.
Slavery (law) is not the solution for the misuse of freedom.
Apostle Paul said "Everything is lawful, but not everything is profitable" (1 Corinthians 10:23). He also said, "do not use your freedom to indulge the flesh; rather, serve one another in love." (Galatians 5:13)
There is another passage which has a lot of implications in it: "Be careful, however, that the exercise of your freedom does not become a stumbling block to the weak." - 1 Corinthians 8:9
Apostle Peter also encourages us saying "do not use your freedom as a cover-up for evil; live as servants of God." (1 Peter 2:16)
What is NOT the solution?
Apostle's solution wasn't suggesting to put us back under the law even while it was a fact they knew very well that people could misuse their freedom and indulge in sin. But, as a solution they did not give a set of principles along with the freedom they preached. In fact, Paul had some strong words against people falling back in to the law.
He said "stand firm in the freedom" and "do not let yourselves be burdened again by a yoke of slavery"
Is there a solution?
I have heard a great analogy about the difference between the country dog and city dog. The city dog usually live inside a fence, restricted from his freedom. So he is always looking for a crack in the fence, so that he can escape from his slavery. and He WILL sneak out, when he get a chance. Whereas, the country dog is totally free, he can go anywhere he wants, there is no fence, law or restrictions. But where would you find him all the time? At the feet of his master! He don't want to go!
He knows his master loves Him. He knows that His master has given him freedom. He sees His master's love and acceptance, and don't want to run away...
Knowing His love is the solution. As we get rooted and established in His love, we don't want to go, we don't want to misuse our freedom. Our desire is Him, His presence, His love and His grace. We realize that the temporary pleasures out there is nothing compared to His love and His presence in life. His grace "teaches us to say 'no' to ungodliness"(Titus 2:12). And as we see this truth, we would start living in His best interest.
