We often hear the quote, "imitation is the sincerest form of flattery." Children might attempt to cook (or pretend to cook) alongside their parents or work on their toy car while their father works under the family car. A budding artist might attempt to reproduce the signature technique of a master artist. In each case, the imitation springs from admiration. Similarly, when we are united with Christ, we are so in awe of who He is that we attempt to imitate his example.
What happens when you use a knife repetitively? Over time, the blade starts squishing tomatoes instead of slicing them.
Pencils need sharpening. Pens need refills, drills need charging. Tools have to be maintained in order to be effective.
In a similar way, we are instruments of God. Are we sharpened, filled, and charged for action? Or, are we gunked up, run down and dull?
