Ensign, November 2009, pg. 33; “The Lord does not expect that we do what we cannot achieve. The command to become perfect, as He is, encourages us to achieve the best of ourselves, to discover and develop the talents and attributes with which we are blessed by a loving Eternal Father, who invites us to realize our potential as children of God. He knows us; He knows of our capacities and our limitations. The invitation and challenge to become perfect, to achieve eternal life is for all mankind.” – Jorge F. Zeballos
Matthew 5:48; “Be ye therefore perfect, even as your Father which is in heaven is perfect.”
The Greek word for perfect is “teleios”. It means growth, mental and moral character, with completeness to full age.
