This is not the way our culture operates - we do things for selfish reasons more than anything. Have you ever taken the time to examine your own motives for decisions you’ve made or are making? It matters. Ask yourself if you’re being patient, or kind, ask God for wisdom.
Sometimes we’re so frustrated by a situation or relationship that we turn off our heart. We grow cold and it makes it easier to be selfish, mean or just to walk away. Sometimes it’s the right thing to do to walk away - IF it’s done in love... For example, leaving a toxic situation to preserve your spirit and prevent sin is love... when we are motivated by fear we give the devil a foothold, when love is our reason he is thwarted.
