Becoming like Jesus in our character and conduct is not instantaneous, it’s a process. Romans 12:2 says “Do not be conformed any longer to the pattern of this world, but be transformed by the renewing of your mind.” The word “transformed” in this verse is the English translation of the Greek word “metamorphosis.”
I don’t know about you but when I hear the work metamorphosis I think of the process by which a caterpillar changes into a butterfly. For this to happen the heart, antennae, reproductive organs, stomach, legs, eyes and brain all have to change. And this doesn’t happen over night! It’s a process. In the same way, as God changes our character and conduct to be more like Christ’s, it doesn’t happen over night. It too is a process.
So don’t throw in the towel if you’re not as much like Jesus as you would like to be. You are a work in progress. Philippians 1:6 says “God, who began the good work within you, will continue his work until it is finally finished on the day when Christ Jesus returns.” The word “began” speaks of our salvation, while the word “continue”speaks of our sanctification. Salvation is instantaneous, but sanctification is a life-long process. In heaven you’ll be perfect, but this isn’t heaven. Don’t get so discouraged by your shortcomings that you quit trying to live your life for Jesus. Making mistakes is part of the change process.
