““All things are lawful for me,” you say—but not all things are beneficial for you. Even though “All things are lawful for me,” I will not be dominated or mastered by anything because not everything is beneficial or edifying.” 1 Corinthians 6:12; 10:23
The Christian is absolutely FREE to do whatever he/she wants, but because he/she has a NEW nature, a NEW heart, and NEW desires, he/she WILL NOT do that which is contrary to “sound doctrine” (your conduct, your behaviour—i.e., “healthy living”; Titus 2:1-10).
Christian liberty has limitations. We may be free from any legal requirements, because we are "no longer under the Law but under grace" (Gal. 5:1; 2 Cor. 3:6-7; Rom. 6:14), but there are still certain practices that are at odds with the Christian life, and no amount of Christian liberty can excuse them. The Christian walks by and after the Spirit—NOT the flesh!
According to these two passages (1 Corinthians 6:12; 10:23), Christian liberty is limited by at least two considerations: (1.) What is the effect of this action upon one's self? (2.) What influence will this action have on "Jews, Greeks or the Congregation of God" as a whole (10:32). Our goal is to seek "the good of others" (10:24), and NOT just our own good (10:33).
Christian liberty is a major theme in Galatians, Paul's first written letter. Given the Corinthian's mantra, "All things are lawful for me," it is quite possible that this was Paul's original teaching to this congregation and that they took it too far and were ignoring the limitations that love for others and holiness before Yahweh place on liberty. The Christian CANNOT live in sin, and when confronted, shrug and say, "All things are lawful for me." Christian liberty ceases to be "Christian" when we engage in acts of immorality and/or fail to truly love one another! First Corinthians 10:31 sums the matter up perfectly: "So, whether you eat or drink, or whatever you do, do all to the glory of God."
“Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness. For sin will have no dominion over you, since you are not under law but under grace.” Romans 6:13-14
