One of the many ways that Mandela exercised great wisdom is in the establishment of what became known as the Truth and Reconciliation Commission in South Africa. As that nation was changing power from non-democratically-elected oppressive minority rule to a truer form of democracy and equal opportunity for all of its people, Mandela recognized that achieving a peaceful and mature society necessitates much more than merely removing legal barriers to justice.
He showed the world that the hard work of authentic reconciliation could not be realized without first dealing with some ugly and painful truths about how that society got to such a state of oppression and how it was perpetuated. His life also gave testimony to the fact that truth telling needs to be inclined towards a loving reconciliation, not merely revenge. One wonders of the progress that the United States could have made if our Civil Rights movement had been allowed to lead to a similar degree of truth and reconciliation.
Although Mandela's application of these principles are largely known in that political setting, every Christian is lovingly compelled by God's Word to deal with a more ultimate manifestation of those principles. In my life, I have to understand that I was lovingly created in God's image and after His likeness. When He made me, He said, "Very good." However, I have a nature that is inclined towards rebellion against God, and without His intervention that rebellion will lead to eternal separation from God. Thankfully, God loves me so much that He gave and sacrificed His only Son so that I can experience loving fellowship with Him now and forever. Thats the ultimate truth which leads to the ultimate reconciliation. That's the Good News for every child of God! That's the Gospel that we must share with this dying world!
