Why is love and charity important among Christians?

In Romans 14, Paul highlights the need for love and charity among believers, noting that our actions should not lead another believer to stumble. He emphasizes that charity—love in action—is crucial as it reflects the love of Christ, who died for each individual. The exercise of liberty must be tempered with love, as our primary goal is to build each other up in faith rather than to flaunt our freedoms. This love is the hallmark of genuine discipleship, as Jesus stated, 'By this shall all men know that you are my disciples, if you have love one toward another.'
