Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another,a forgiving each other, just as in Christ God forgave you.(Eph 4:31-32 NIV)
He stands not as a mediating principle but as the Person, the Lord, controlling all things in between. His mediatorship affirms His centrality and sovereignty over our lives. Nothing happens by chance or human whim when He comes in between. Therefore, there can be no room for fear, for worry. There can be no room for bitterness or unforgiveness, because whatever happened happened because He has mediated and intervened.
A young man feels angered at another man for doing something to him that is hurtful. Suddenly, there is a surge of bitterness and hurt. Not that he wishes to hurt the other; but, there is a feeling of pain. But, then he is reminded that whatever has happened has not happened outside the knowledge and control of our Lord. Also, when the Lord comes in between I have no right to hold any grudge against any other. I cannot grudge against what He has allowed; because whatever He allows is for my good, though it be painful. I cannot leave unforgiven what He has already forgiven.
