All religions have at their core, a system of self-sacrifice. At first glance, sacrifice seems noble and honorable. Sacrifice is seen as the means with which we please God; that somehow He loves us more based on what we have given up for Him. Currently we are finishing up the season of Lent. The whole idea behind Lent is that we sacrifice something dear to us in order to identify with God.
Jesus speaks some interesting words about sacrifice. Twice He quotes the prophet Hosea -
"I desire mercy and not sacrifice". Both times He was accosted by the religious for failing to meet their expectations - once when He socialized with sinners and once when He allowed His disciples to pick and eat grain on the Sabbath.
Perhaps God is not as interested in our sacrifice as He is in our attitude toward other people. One of the dangers of sacrifice is that it can quickly breed judgmentalism toward other people. About a year ago I was at a cattle sale. As I observed people and their activities, I felt God speak to my heart. For some time, I had been bothered by the attitude of Christians. A web forum in which I participate had an ongoing debate about judgment. It seemed to me that some people relished the thought of the heathen "getting theirs" someday. As I watched the people at the sale, I realized that many Christians feel they have sacrificed a lot to be "good Christians". With that sacrifice comes a fear that the "world" is having a good time all the while we are in misery from our sacrifice. We console ourselves with the thought sometime in the future the bad people will be forced to pay for their misdeeds.
Like the elder brother in the story of the prodigal son, we have stayed home and been good. Our preoccupation with our sacrifice renders us unable to rejoice when the prodigal comes home. In our mind, it's not fair. It seems as if he is being rewarded for his sin while we are being ignored. Therefore we begin to be judgmental and harsh. We demand recognition from the Father for our sacrifice, thereby missing the point completely.
About right now, someone is saying "yeah but Jesus said we have to die to ourselves". That is true, However, the point of dying to ourselves is not to impress God but to move from self-destruction to abundant life. If our dying to self does not create the character of Jesus within us, then our dying is in vain. Jesus simply stated that if we are going to follow Him, we will be forced to take up our cross. He never stated that sacrifice will cause us to follow Him. If we focus on sacrifice we have missed the point.
