You care for someone, but you don't care for their behavior. The old adage "Keep your friends close and your enemies closer" has application here. Influence comes with relationship, so move toward them however you can so that your heart and love for them will soften their heart toward what you're saying. Avoid frequent confrontation; that will only push them away. Look, you're not tolerating their poor choices; you're trusting that closeness has more redemptive influence than distant judgment.
