From Paul Tripp’s What Did You Expect?:
Remember, the God who made lilies also made rocks. As creator, God has invested his world with difference; all things are not the same. He has made people widely different from one another. All this reflects his glory. And as sovereign, he chooses to bring different people into intimate relationship with one another for his honor and their good. Unity is not the result of sameness. Rather, unity results when love intersects with difference.
It is self-love that hates difference. It is self-love that makes you impatient. It is self-love that makes you want your own way. It is self-love that convinces you that your way is the right way. It is self-love that makes winning more attractive than unity. Love celebrates who God has made the other person to be. Love celebrates the process of working together to become one. Love celebrates the grace of change that operates in the middle of the difficulty of difference. Love prizes unity and is willing to make sacrifices to achieve it. Love turns difference into an opportunity to experience a deeper and fuller unity. Love isn’t impatient, and it does not walk away. Love perseveres. Love stays active until what God has planned becomes your actual experience. Love listens, works, and waits. Unity happens when love intersects with difference.
