Good morning! This passage of Scripture is to the saved. It is a reminder that we can't let the things of this life change us or how we love one another. Not personal differences, doctrinal differences, personal preferences, worship styles, denominational lines, liturgical differences, personality conflicts or Bible translations.
If our love is conditional to our being exactly the same, we will never love like God or live like Jesus. We close off our hearts to the love of God abiding in us. We leave no room and shove Him out for our own preferences.
His love has to be perfected in us that when we see someone, we love them the same way God does. He loves without partiality or discrimination and so should we. Let His love be perfected in you that no matter who you encounter, you can love them the same way. Than you will have the love of God abiding in you and be able to make every day a great day!
