9 Not because of works [not the fulfillment of the Law’s demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.]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].11 Therefore, remember that at one time you were Gentiles (heathens) in the flesh, called Uncircumcision by those who called themselves Circumcision, [itself a mere mark] in the flesh made by human hands.12 [Remember] that you were at that time separated (living apart) from Christ [excluded from all part in Him], utterly estranged and outlawed from the rights of Israel as a nation, and strangers with no share in the sacred compacts of the [Messianic] promise [with no knowledge of or right in God’s agreements, His covenants]. And you had no hope (no promise); you were in the world without God.
What we have been given by God is not due to anything we have done. It is not because of our works, so we cannot have pride in what we have been given from Christ. It is only through God’s work on the cross that we are able to boast. He did it all, so we could have it all.
We are God’s own handiwork(his workmanship). We are crafted from God. He took care and time to create us. We are recreated in Christ. So, he created us, then recreated us in Christ when we were born again. Now, due to the recreation, we are able to do good works. The good works were planned by God ahead of time. He wanted us to do good works so we can live the good life that God arranged for us.
At one time, we were living apart from Christ and had no promise, we were in the world without God.
