We as grace believers in this age of the pure grace of God must never flaunt our liberty so as to offend other believers who do not have that revelation of truth and liberty we now have and enjoy “in Christ.” Paul offers this verse is a great and guiding principle of the Christian life.

 “Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God” (I Cor. 10:31).

The Apostle Paul points out in the preceding context that what may be perfectly right for one person to do may trouble another’s conscience. The sincere and gracious believer who enjoys the liberty of living under “the grace of God” and the Lord’s forgiveness, therefore, will not push and carelessly violate his brother’s conscientious principles, offending him by indulging in that which he may consider wrong. This of course does not say we should avoid honest fellowship and sharing our faith in God’s grace if the other brother seems open to such discussion. There are times we should shut our mouth and others when we can feel free to share the principles of the “grace of God” that we have come to see and enjoy.

Thus Paul also wrote this below concerning our attitude and interaction with a “weak” brother who still thinks he must keep the external laws of Judaism.

“AS FOR the man who is a weak believer, welcome him [into your fellowship], but not to criticize his opinions or pass judgment on his scruples or perplex him with discussions. 2 One [man's faith permits him to] believe he may eat anything, while a weaker one [limits his] eating to vegetables. 3 Let not him who eats look down on or despise him who abstains, and let not him who abstains criticize and pass judgment on him who eats; for God has accepted and welcomed him. …  5 One man esteems one day as better than another, while another man (the grace believer) esteems all days alike [sacred]. Let everyone be fully convinced (satisfied) in his own mind. 6 He who observes the day, observes it in honor of the Lord. He also who eats, eats in honor of the Lord, since he gives thanks to God; while he who abstains, abstains in honor of the Lord and gives thanks to God. 7 None of us lives to himself [but to the Lord], and none of us dies to himself [but to the Lord, for] 8 If we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or we die, we belong to the Lord. (Romans 14:1-3, 5-8 (AMP)

In Paul’s day, this particularly involved the foods of which men partook according to Jewish dietary laws. Of course today under “the dispensation of the grace of God” we are not vegetarians as Adam was, or kosher eaters as seen in Leviticus. Paul says of us today; ^“For every creature of God is good, and nothing to be refused, if it be received with thanksgiving ⁵ For it is sanctified by the word of God and prayer.” (1 Timothy 4:4-5).

So from both Romans 14 and I Corinthians 10 it is evident that Christian conduct in general is involved in interacting with religious law-keeping believers.

If, in my daily conduct, I consider not only my own, but also my brother’s conscience, it does not follow from this that I am disobeying Gal. 5:1, failing to “stand fast… in the liberty wherewith Christ hath made us (me) free.” True, I have no right to give up my blood-bought liberty, but… I do have liberty to be gracious in giving up my rights… so as to no offend another. This attitude is one of the signs of our regeneration in spirit.

My aim in life should not be to gratify my own desires, or to to show up my brother’s weaknesses by vaunting my liberty in Christ. My one aim should rather be to glorify God in all I say and do.

All this, of course, has to do only with the conduct of a believers walk in Christ. The unbeliever can do nothing to the glory of God. His very rejection of Christ is a continual offense to God who, in love, gave His Son to die in our place. The only way in which the unbeliever can honor God is to turn from his unbelief and trust Christ as Savior and Lord.
