Christian freedom is inseparably tied to Christian responsibility. Some actions may be justifiable and lawful but they may be harmful to others due to their limited exposure or age in the faith. Christian believers should be spiritually sensitive enough to avoid those things that will affect others negatively.
But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea. (KJV)
But whoever causes one of these little ones who believe in and acknowledge and cleave to Me to stumble and sin [that is, who entices him or hinders him in right conduct or thought], it would be better (more expedient and profitable or advantageous) for him to have a great millstone fastened around his neck and to be sunk in the depth of the sea. (Amplified)
Our love for others and the glory of God will make us exercise our freedom with caution and prudence, lest we become a stumbling block on their way to heaven.
