"Notice that in order for obedience to take place the Lord must first cleanse our hearts, put a new spirit in us and remove our hardened uncircumcised heart. No one believes and obeys while their heart is still stone. Our blind eyes must be opened, our deaf ears unstopped, and our corrupt nature supernaturally changed by the Holy Spirit, before we can begin to have any good thoughts about Christ. The Bible likens the new birth, or regeneration, to the first creation (2 Cor. 5:17). God let light shine into what was darkness. And God breathed life into lifeless man and then man, because of the new principle of life now within him, breathed and walked. Likewise regeneration can be likened to God's first breath in man, and faith, to Adam's first breath. The former is monergistic and the later, while it springs from the principle of grace that now exists within, is participatory. Both the creation and the maintaining are all of grace, but only God's breathing life into us (ex nihilo) is monergistic (that is, it is the work of God alone). When God brings forth something out of nothing, it is monergistic, but when we breathe (or have faith) as a result of God's act, we are now participating, so by definition this is not monergistic, but all springs forth from God's initial monergistic act of giving life from nothing."
