Half-life (t½) is the time required for a quantity to fall to half its value as measured at the beginning of the time period. When it comes to evangelism gadgetry or methodology, it suffers the same exponential decay. I’ve seen all the gadgets and all the methods. I’ve seen them used and abused. I’ve seen the initial wow effect and the minimal long-term impact.
I do understand the need for confidence in proclaiming the gospel. I also understand the need to have a system in place to prevent the gospel stutter. The problem comes when those we’re trying to transmit the gospel to, unwind our presentation. We’re often left looking weak and worse ignorant of the good news itself. Not only is the gospel emptied of its power, but the very tools or methods we use as a delivery system also suffer impact decay.
So, if this theory of mine holds true, what can we do to prevent an incorrect, incomplete, and inept gospel message?
