For some non-believers, the necessary leap of faith immediately nullifies any claim of truth because they believe scientific knowledge is the end-all and be-all of truth. I suspect, though, that many of the staunchest materialists' rejections of Christianity do not rest solely on their insistence upon empirical proof but are combined with their experience with Christians who are close-minded, judgmental, and hypocritical. In short, if a lack of empirical evidence doesn't solidify their atheism, then Christians themselves seal the deal.
This brings me to the question I posed at the end of my first FoF post: If we can't prove our faith, then how are we to reach the world? I believe the church in America has spent far too much time avering the idea of having a "personal relationship with Jesus" and far too little examining what it is to be an imitator of Christ. The call of Christ is not a call to let Jesus be our buddy. It is not a call to a pursuit of our ambitions and material whims, with the assumption that God wishes the fulfillment of such things for His people. It is not a call to condemn the non-believer. It is not merely obstaining from sin. It is not a call to provide philosophical or scientific proofs of His existence. It is not a call to feeling good all the time. It is not a call to attend corporate worship three times a week, observing traditional practices and elevating them to divine commandments. It is not legislating morality.
What is it then to imitate Christ? It's nothing less than emptying ourselves in love. In John 13:34, Christ says, "A new command I give you: As I have loved you, so you must love one another. By this all men will know that you are my disciples, if you love one another." If we pray "Thy kingdom come, thy will be done, on earth as it is in heaven," then we need to recognize our role in furthering God's kingdom. Christ showed compassion to the hurting, welcomed the rejected and outcast, extended mercy and grace to the sinner. He emptied himself, and we are called to do the same--Philippians 2:5+
Father, fill us with your Spirit. Transform our hearts and minds into a likeness of Christ. May the fruits of our actions be sweet nourishment for the suffering, the searching, and the lonely, not something bitter or rancid they spit out. May we love with abandon.
