That's easy. 2 Cor. 5:14-21.
In part, "And all things are of God, who hath RECONCILED US to HIMSELF BY JESUS CHRIST, and hath COMMITTED UNTO US THE WORD OF RECONCILIATION. Now then we are AMBASSADORS for Christ, as though God did beseech you BY US; we PRAY YOU IN CHRIST'S STEAD, BE YE RECONCILED TO GOD. For he hath made him to be sin FOR US, who knew no sin; that we might be made the righteousness of God in him."
And what else might God want us to be?
2 Timothy 2:15. "STUDY to shew thyself APPROVED UNTO GOD, a workman that needeth NOT TO BE ASHAMED, RIGHTLY DIVIDING THE WORD OF TRUTH."
The question you answered is indicative of the attitude that man can somehow by his own actions be justified. Institutionalized religion has failed the masses in so many ways.
