4 Bible Verses about Human Imperfection

For in many things we all offend. If any one offend not in speech, the same is a perfect man, able to bridle the whole body also.

Not that I have already obtained, or have been already perfected; but I press on, if I may also lay hold of that for which I was laid hold of by Christ.

Be watchful, and strengthen the remaining things, that were ready to die; for I have not found thy works perfect before my God.

but when that which is perfect is come, that which is in part will be done away.
