One way to tap latent potential is to embark on something humanly impossible. While others are able to get away with minor errors, you will not. The results of your internal deviation are instant. It is one way to ensure strong spiritual development because you are automatically kept in line and wholly dependent on the Spirit because of the impossibility of the endeavor.
Peter began to sink, just because he deviated in his mind, where no one saw him but God. Had he been in the safety of the boat, there would have been very little possibility of sinking, he might not have realized he was out of alignment and would have had no need to call on Jesus.
Limiting yourself to what is humanly possible and easy guarantees mediocrity because you easily get away with indiscipline and base appetites. Safety is dangerous. Stepping out on the impossible causes you to be disciplined because survival often depends on it. One of the best things anyone can do for themselves and for the world is to put themselves in situations where survival requires Christlikeness.
If your aim is to make it through the day, eat, drink, sleep and be comfortable, you may not have to worry about minor errors. If your task involves being the light of the world and creating new pathways, you cannot afford the slightest deviation. A foam hitting a moving car is nothing to worry about but when it hits a space shuttle, disaster looms.
By calling on Jesus when fear caused him to begin sinking, Peter recovered immediately and walked on water back to the boat. Your journey through the uncharted does not have to end if you fall. Christ who invites us into the uncharted is also the very present help in trouble who enables you get right back on track when you fall. Isn’t He a no-brainer in a world that desperately needs people bold enough to step out of the boat?
