I would love to be a fly on the wall if you quoted those verses to him Kaylz!Romans 12 also has some good stuff about patience and perseverance.
v17-18 "If it is possible, as far as it depends on you, live at peace with everyone."
v16 "Live in harmony with one another."
vv9-10 "Love must be sincere. Hate what is evil; cling to what is good. Be devoted to one another in love. Honour one another above yourselves."
v12 "Be joyful in hope, patient in affliction, faithful in prayer."
