I love the martial arts choreography in movies like Crouching Tiger Hidden Dragon. I asked a black belt friend how he hardened his hands for real (not staged) competition. It seemed simple enough. Set up a five-gallon bucket of white rice and punch your hands in it 10-12 times in a row five times a day. When that no longer hurts use a five-gallon bucket of dry beans for several weeks and then graduate to five gallons of sand. 

While it takes time to become hardened it is a simple process. My martial arts friend cautioned me “Be careful. The process is irreversible once the calluses are there….and you could really hurt someone with them.” 

Similarly I’ve discovered a way to build calluses on the heart – especially this time of year. Plunge your hands five times a day into websites television and email coming from nonprofits and ministries. When the numbing is sufficient start on your direct mail stack and personal letters. When all the feeling is gone move up to repeated plunging into personal visits phone calls and notes from friends. For the final hardening dwell on all the disappointments misused gifts unrealistic expectations and relentless pictures of children and women. By then you should have to register your heart as a lethal weapon and warn people before meeting them. 

Is that really what God wants? I believe what He desires instead is for us to resist becoming hardhearted. What I have discovered and heard from others is this: resistance builds heart muscle not calluses. Constant outside pressure builds calluses. Patient practice of giving skills builds strength but constant exposure to irritation builds calluses. Muscles are alive and growing. Calluses are dead and hard. There is no way to avoid the predictable barrage of incoming requests for help – especially in this economy and season. Focus on the few things that matter most to you and refuse to let your heart mind and soul become hardened. The process is irreversible for hands…but not for hearts.
