delvanis,

You must look at the implications of your assertion that man has freewill to repent and believe. If man does have freewill to repent and believe, then God is ultimately not sovereign. You make God dependant on man and therefore He is frustrated many, many times over those who never repent and believe. The result is the glory for our repentance and belief goes to man or at least is shared between God and man.

God gets all of the glory for our ability to truly repent and believe. This then squares perfectly with the Bible that we cannot boast in it. (Eph 2:9)

Also, if man has freewill to repent, then why does the Bible speak of God being the one who "grants" repentance: "...if God perhaps will grant them repentance, so that they may know the truth." - 2Ti 2:25

Who does the appointing here? "And as many as had been appointed to eternal life believed." - Act 13:48b

Who's doing the choosing and causing here? "Blessed is the man You choose, And cause to approach You..." Psa 65:4
