"Patience requires both faith and humility. It requires that whenever things go differently than we envision or wish, we believe that God is working all things for good (Romans 8:28), that he will complete all the good things he begins (Philippians 1:6), and that we can trust him because our understanding is incomplete and inaccurate at best (Proverbs 3:5-6). Patience is not permissive; it doesn’t think sin or injustice is okay. Neither is patience passive; it doesn’t do nothing. It is just a relentless trust in all that we do, and all that we cannot do, that God will deal with everything in perfect justice (Deuteronomy 32:4). And he will accomplish all his purposes (Isaiah 46:10). Therefore we do not need to get angry. Ultimately, love is patient because God is patient: “The Lord is merciful and gracious, slow to anger and abounding in steadfast love” (Psalm 103:8). And that’s why we are to be “quick to hear, slow to speak, [and] slow to anger” (James 1:19)." - https://www.desiringgod.org/articles/love-is-patient
