You are predestined for great works by God’s grace!
For it is by free grace (God’s unmerited favor) that you are saved… 9 Not because of works…
10 For we are God’s [own] handiwork (His workmanship), recreated in Christ Jesus, [born anew] that we may do those good works which God predestined (planned beforehand) for us [taking paths which He prepared ahead of time], that we should walk in them [living the good life which He prearranged and made ready for us to live]. Eph 2:8-10 AMP
You do not need to volunteer, you have already been called
“Who were chosen and foreknown by God the Father and consecrated (sanctified, made holy) by the Spirit to be obedient to Jesus Christ (the Messiah) and to be sprinkled with [His] blood: May grace (spiritual blessing) and peace be given you in increasing abundance [that spiritual peace to be realized in and through Christ, freedom from fears, agitating passions, and moral conflicts].” 1 Peter 1:2 AMP
“…elect according to the foreknowledge of God the Father, in sanctification of the Spirit, for obedience and sprinkling of the blood of Jesus Christ: Grace to you and peace be multiplied.” 1 Peter 1:2
elect = eklektos, ek-lek-tos’; from Greek 1586 (eklegomai); select; by implication favorite :- chosen, elect.
