Loving people as they are seems like a rather straightforward idea. However, for the most part, it seems that we love people as they are but we also expect they will change. Specifically they will change that thing that we do not love. We might love our children, but expect they will grow out of some unfavorable behavior (like throwing tantrums). We might love our parents, but expect they will grow out of treating us like we are perpetually ten years old. We might love our partner, but expect that over the years they will change and put the dang seat down!
We might even love God, but expect God to change in how God interacts with the world (like eliminate sin).
The thing about loving people as they are but expecting them to change is that we will never love them.
If the person you love changes in the way that you would hope they would change, then you will find some other feature about that person that you wish they would change. It is an endless cycle. We will not be able to love them because we will end up hating the new thing they become in a different way.
You child grows out of throwing tantrums, but now they repress their emotions and you wish they would change that. Your parents treat you as an adult, but now they are pressing you to have children of your own, and you hate that. Your partner finally puts the seat down, but now you are annoyed that they let dishes “soak” for three days!
Even when God eliminates sin, God now welcomes the former sinner into the kingdom and you wish that God would see that “those people” are freeloading on forgiveness.
We are faced with the paradox to love people as they are and not expect them to change, or never loving them at all.
