Do we still need to cry out for God's mercy?
No, believers no longer need to cry out for God's mercy, because God poured out His mercy on Christ at the cross. Since that mercy has already been poured out, God now extends grace—unmerited favor—which is not deserved. There is nothing in us that merits favor with God.
Les explains that mercy was poured out on Christ at the cross, so the believer no longer has to cry for mercy; it has already been poured out. Because of that, what God now gives is grace—unmerited favor—which we do not deserve. He stresses that nothing in us can merit any favor with God; it is all of His grace, and grace could never have happened without mercy. He also notes that in all these things we are more than conquerors through Christ Jesus, not through any ability of our own.
