I know that we won't be sinless until glory, but Paul said we could be "perfect":
2 Corinthians 13:11 Finally, brethren, farewell. Be perfect, be of good comfort, be of one mind, live in peace; and the God of love and peace shall be with you.
Philippians 3:15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you.
2 Timothy 3:17 That the man of God may be perfect, throughly furnished unto all good works.
What do you think it means to be perfect? How does one become perfect in this life?
