Let me rephrase for you:
A Very Rich Man gives you a RM1 Million Lamborghini out of his grace.
He tells you like this:
I give it to you FREELY as my act of Grace, but you just have to accept it.

I think the answer you are seeking may lie in John 6:25 onwards.
God has given us grace for us to freely respond to. By His sovereignty He has determined who will seek this salvation. We choose to respond to God's calling because He had first reached out to us that we will be sent to Christ, hence our response of acceptance by itself is bestowed upon God's grace. From a human perspective it is "We choose to accept Jesus", but from the eyes of God it is "You were chosen by Me!"
If God can provide us with the appropriate response to His calling, He will also provide us with the Holy Spirit for repentance.
Had been doing a bit of a read up recently about Human Responsibility in line with God's Sovereignty. Understanding this is still out of this world for me, but hopefully I'll be there one day. Maybe...
