Propitiation

"Propitiation in the context of salvation means that which appeases the wrath of God against sin. So the Lord Jesus Christ by His sacrifice on the cross appeases and turned aside God's holy and just wrath, the wrath that we should have bore." Bridges
What does this mean in application to us is that if Gods wrath for our sin was exhausted on Jesus at the cross , then there is none left toward you, Ro. 8:1 There is therefore no condemnation.
In Topladys hymn, From Whence the Fear and Unbelief, he writes, "Payment God CANNOT twice demand, First at my surety's hand and then again at mine. This is the good news It really does not matter how you "feel" at any given moment the reality is you no longer EVER have to fear Gods wrath on your life it's not necessarily how we view the death of Jesus on the Cross it's how God views it.

"It is not our contrition or sorrow for our sin, it is not our repentance, it is not even the passing of a certain number of hours during which we feel we are on some kind of probation that cleanses us. It is the blood of Christ, shed once for all on Calvary two thousand years ago but appropriated daily or even many times a day, that cleanses our consciences and gives us a new sense of peace with God." Bridges
It is arrogance or ignorance that we think that we can go before God pointing to some good work or meritorious work that we have preformed, good works are right but those works do not contribute in anyway towards your standing with God, the only work that God recognises is Christs work and death.

"This standing in Christ's righteousness is never affected to any degree by our good day bad day performance" Bridges
Gods anger and wrath toward sin was "Propitiated" spent on, exhausted on Jesus at the Cross so that for all those who have trusted in Christ as their only hope of salvation never have to fear Gods wrath again in their lives, His discipline YES but never His wrath. Our standing with God is secure, often tough to belive but true.
