The new covenant is God not merely giving us a human mediator but the second member of the Trinity Himself coming into human history as the man Jesus Christ. This time, rather than taking life as He did when He flooded the earth in the days of Noah or requiring sacrifices for sin in the Mosaic covenant, He offered Himself as the sacrificial substitute for sinners on the cross where He shed His blood in their place.

The way of godliness consists of these two parts, pious doctrine and good works. Neither are the doctrines acceptable to God without good works, nor does God accept works accomplished otherwise than as linked with pious doctrines. Cyril of Jerusalem (315-386)
I am, then, first and foremost unlearned, an unlettered exile who cannot plan for the future. But this much I know for sure... I was like a stone lying in the deep mud. Then He who is mighty came and in His mercy He not only pulled me out but lifted me up and placed me at the very top of the wall. I must, therefore, speak publicly in order to thank the Lord for such wonderful gifts, gifts for the present and for eternity which the human mind cannot measure.
as translated by Joseph Duffy in Patrick in His Own Words, Veritas Publications, 1972
My brothers, let each of you present himself before the face of the Lord, and confess his faults and sins, following my words in his heart; O Lord God, eternal and almighty Father, we confess and acknowledge truthfully before Your holy majesty that we are poor sinners, conceived and born in iniquity and corruption, prone to do evil, incapable of any good, and that in our depravity we transgress Your holy commandments without end or ceasing; therefore, we purchase for ourselves, through Your righteous judgment, our ruin and damnation. Nevertheless, O Lord, we are grieved that we have offended You, and we condemn ourselves and our sins with true repentance, begging Your mercy to relieve our distress. O God and Father most gracious and full of compassion, have mercy on us in the name of Your Son, our Lord Jesus Christ. And as You blot our sins and stains, magnify and increase us day by day the grace of the Holy Spirit, that as we acknowledge our unrighteousness with all our heart, we may be moved by that sorrow that shall bring forth true repentance in us, mortifying all our sins and producing in us the fruit of righteousness and innocence that are pleasing to You, through the same Jesus Christ our Lord. Amen.
