True Christian love is defined by its actions under pressure, not merely by feelings or theoretical knowledge. When confronted with offense, disagreement, or another's success, our natural inclinations toward envy, pride, and resentment are exposed. Paul’s portrait of love in 1 Corinthians 13 acts as a divine mirror, compelling us to allow the Holy Spirit to kill our selfishness so that authentic, enduring Christlike love can flow through us.
