Unconditional means complete and absolute. So, the question is Who do you think can give you a complete and absolute love?.
Clarifying the facts of unconditional love is pretty much interesting. "Agape" Love is the only love that has been written and known as the unconditional one and that is God's love to His children and that includes you. Parents love to their children is genuine, real and out-pouring. They loved them with much care and support, protecting them from any harm and willing to sacrifice everything for the good sake of their children. And they deserved to be honored and be appreciated. But only God can give us the love that is the unconditional one that we’ve been looking for. Despite all the sins that we made each day but still, God's love is always there. He never forsakes us. He cares for us, forgives us, protects us, providing us our needs, guides and gives us a good health every day. He even died for us to have an everlasting life. Who else can do these amazing things to us? Only God can do it because He loves us unconditionally.
God is everything and no one can ever compare with His love to each and every one of us because His love never fades and never fails.
