How should Christians respond to phrases like 'good luck'?

The use of phrases like 'good luck' can often arise from habit rather than belief in their secular implications. As Christians, it is important to approach such phrases with grace and a spirit of inquiry, seeking to understand the true meaning behind the words spoken. Hastily judging fellow believers based on their language can lead to misunderstanding and division within the body of Christ. We are called to extend charity and patiently discern the intentions of others, recognizing that our communication is imperfect but covered by grace.
