Is It God's Gift to Mankind?

I like to believe that God is Omnipotent and well... very very smart. I would say his grace was a huge gift to mankind. I would assume it safe to say that God giving up of himself to send his son to earth to die on the cross for the sins of mankind is a huge gift. All the incredible things God created from the earth, animals, even Sex {(between husband and wife, of course;-)} What about Free Will? Is Free will a Gift or a curse? God gave us the ability to choose our actions. Whether you believe in predestination or not. Free will is perplexing and Ironically up to you if it really is a gift or a curse. The path you take with your thoughts and actions decide if it is a curse or not. Free Will is the one thing and the only thing that God gave you that you have complete control over. So you have this Ginormous thing that God has given you and what you do with it is up to you. Curse or Gift?
