We cannot, this side of Heaven, yet Jesus commands it.
Matthew 5: 48 So be perfect,* just as your heavenly Father is perfect.d
So what are you going to do? Ignore Him?
We WILL BE PERFECTED!!!! Just as Jesus commands!
This is a process, which we are undergoing, and Jesus is the author and perfector of our faith.
WHEN will we be perfected? the 100% mark occurs at OUR DEATH, or assumption (whichever comes first). Short of this we are all fallible.
Now you tell me, are YOU PERFECT? Have you ever made it through a day, week, month? Does Jesus grade on a curve?
Of course any Christian wishes to be perfect, we just cannot do it completely in this life. Not ONE of us.
Now tell me -— are you perfect? If not, do you not believe the scripture? or are you just tilting at windmills?
