Ever cooked anything that required continuos stirring until it was done? Believers are sort of the same, just in case anyone considered themselves perfect. The reality is we are works in progress. We fail and have our flaws, but God is continuously stirring things up in our lives as He molds us. We are many things; believers, saved, redeemed, but perfect isn’t one of them and that’s ok because God isn’t finished with us yet.
And I am certain that God, who began the good work within you, will continue his work until it is finally finished on the day when Christ Jesus returns. (Philippians 1:6 NLT)
