Drawing Back from a God of Unconditional Love?

At church this morning, the pastor's sermon was about God being a God of relationship.  The pastor said that God was sufficient in himself, but God's love overflowed, as God created human beings to have a loving relationship with them.  The pastor also said that many are apprehensive about entering into a relationship with God because they fear losing their own individuality.  But the pastor went on to affirm that God is okay with our individuality----that God wants to use us to help others, with our strengths and weaknesses.

Why would people be afraid to enter into a relationship with a God who unconditionally loves them?  "Because they want to do anything they want, without being accountable to a higher power," Christians may respond.  But if God's love is truly unconditional, that would mean that God loves people even if they do what they want, right?  Why wouldn't anyone want to be in a relationship with that kind of God?  I think that one reason that some might not want to be in a relationship with God is that they don't really think that God's love is unconditional.  Moreover, my impression is that the monotheistic religions do not consistently present God's love as unconditional.
