We are new creatures created in Christ Jesus to do good works and walk in them.
“For we are God’s own handiwork, created in Christ Jesus for good works which He has pre-destined us to practise.” Ephesians 2:10 WNT
“For the love of Christ overmasters us, the conclusion at which we have arrived being this—that One having died for all, His death was their death, and that He died for all in order that the living may no longer live to themselves, but to Him who died for them and rose again. Therefore for the future we know no one simply as a man. Even if we have known Christ as a man, yet now we do so no longer. So that if any one is in Christ, he is a new creature: the old state of things has passed away; a new state of things has come into existence.” 2 Corinthians 5:14-17 WNT
Regarding good works, Kretzmann wrote this on Ephesians 2:
Thus faith is the beginning of the new spiritual life. In this work of spiritual regeneration, of quickening to new life, all cooperation on the part of man is expressly and emphatically excluded. God’s free gift and gracious present it is, not a reward for works performed by man by which he might have made himself worthy of being regenerated in the sight of God; no merit in us was considered,The Popular Commentary of the Bible by Paul E. Kretzmann, Ph. D., D. D., has been a favorite among confessional Lutherans since publication of the first volume in 1921. http://www.kretzmannproject.org/
The emphasis again is on the side of God; it is God who gave us the position which we hold as Christians. It is God, also, who performed the work of the new creation in us, so that we are in the fullest sense of the word the work of His hands, fashioned by Him in Christ Jesus, through whose redemption and life we have received the new spiritual life. By virtue of this new life, which is here again, in its totality, ascribed to the creative power of God, we are prepared for good works, we are able and ready to perform such deeds as are pleasing to our heavenly Father.
These good works, which are the evidence of the new creature in us, by which our Christianity is tested and approved, have been made ready and set forth by God before we ever thought of performing them. God is the unseen Source from which the good works spring, His creative power is their final explanation. And by and through our fellowship with Christ these good works are performed in us; Christ, in whom we live and move and have our being, makes us partakers of His gifts and virtues, is expressed in our life and conduct; Christ’s holiness, purity, humility, meekness, benevolence, and kindness appear in the lives of the Christians. And so all glorying on the part of the believers is excluded, as a matter of fact is never indulged in. A true Christian does not even boast of the good works which it is his privilege to perform, knowing that it is the power of Christ and God in him that enables him to follow the example of Christ.
