A.B. Simpson emphasizes the principle of love in Christian freedom, arguing that while one may have the liberty to engage in certain activities, it is crucial to consider how those actions may affect others, particularly their conscience. He advocates for the surrender of personal indulgences to prevent causing temptation or harm to fellow believers. Simpson highlights that many seemingly harmless activities can lead to worldliness and should be avoided if they pose a risk to others' spiritual well-being. The essence of Christian character is revealed in the thoughtful love that guides our choices, demonstrating the importance of prioritizing love over personal freedom.

I may be perfectly free myself to do many things, the doing of which might hurt my brother and wound his conscience. Love will gladly surrender the little indulgence so that my brother may be saved from temptation. There are many questions which are easily settled by this principle. So, too, there are many forms of recreation which in themselves might be harmless and, under certain circumstances, unobjectionable, but they have become associated with worldliness and godlessness and have proved snares and temptations to many a younger Christian. In that case, the law of love would lead me to avoid them, discountenance them and in now way give encouragement to others to participate in them. It is just in these things that are not required of us by absolute rules, but are the impulses of a thoughtful love, that the highest qualities of Christian character show themselves. It is in these that the most delicate shades of Christian love are manifested.
