When car enthusiasts must decide on new wheels, the capacities of different features come under severe scrutiny. Things like engine size, torque, liters per kilometer, braking power, acceleration and range weighs more than the price tag.
Different humans also has different capacities and God knows how far He can go with each of us. He knows our pain ceiling, how patient we are, how charitable our hearts are. He knows when we are plain lazy, capable of doing much more or going along at full throttle.
Let us not under-perform for God who knows our capacity.
