I have been thinking a lot about the issue of redemption and reconciliation. God's unconditional love emphasises reconciliation but reconciliation comes through being drawn to repentance. God doesn't love us regardless. He loves us so that we might see our faults and turn to Him in repentance. We have to learn to love in such a way that those who we interact with will seek to re-establish relationships. It is so easy to close the door and end all contact but that isn't God's way. We have to extend our love and reach out to the pain of others. Our goal is to reconcile others in the relationships that are around them.
The next thought is that God's unconditional love still keeps loving even though the recipient closes the door. This makes the love hard to communicate but at some point the door has to open and the love will flow in.
More from a human perspective God's love means working to resolve conflict by seeking to understand. It is easy to blame everything on the other person and fail to see where we haven't shown the love and compassion that we should have. Even when others don't respond, we have to learn to continually try and communicate.
God must also feel the barriers when we endeavour to shut Him out because we have acted contrary to His wishes.
