Unconditional Love

What is “unconditional love” and can humans actually practice it?

I think this is a struggle because we as humans are fallen and sinful and our perceptions of things like love are skewed and don’t always line up with God’s definitions. I’ve heard many people and even Christian songs on the radio talk about how God loves us “just as we are” and He loves “people like us” and I agree. To a point.
