Matt 5:48 - Be ye therefore perfect, even as your Father which is in heaven is perfect
In Matt. 5:48, the term perfect was translated from the Greek teleios, which means “complete.” Teleios is an adjective derived from the noun telos, which means “end.” The infinitive form of the verb is teleiono, which means “to reach a distant end, to be fully developed, to consummate, or to finish.” Please note that the word does not imply “freedom from error”; it implies “achieving a distant objective.” In fact, when writers of the Greek New Testament wished to describe perfection of behavior—precision or excellence of human effort—they did not employ a form of teleios; instead, they chose different words.

In this life, certain actions can be perfected. A baseball pitcher can throw a no-hit, no-run ball game. A surgeon can perform an operation without an error. A musician can render a selection without a mistake. One can likewise achieve perfection in being punctual, paying tithing, keeping the Word of Wisdom, and so on. The enormous effort required to attain such self-mastery is rewarded with a deep sense of satisfaction. More importantly, spiritual attainments in mortality accompany us into eternity.
Mortal perfection can be achieved as we try to perform every duty, keep every law, and strive to be as perfect in our sphere as our Heavenly Father is in his. If we do the best we can, the Lord will bless us according to our deeds and the desires of our hearts.

The perfection that the Savior envisions for us is much more than errorless performance. It is the eternal expectation as expressed by the Lord in his great intercessory prayer to his Father—that we might be made perfect and be able to dwell with them in the eternities ahead.
Eternal perfection is reserved for those who overcome all things and inherit the fulness of the Father in his heavenly mansions. Perfection consists in gaining eternal life—the kind of life that God lives.

Matt 19:21 - Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.
22 But when the young man heard that saying, he went away sorrowful: for he had great possessions.
Moroni 10:32 Yea, come unto Christ, and be perfected in him, and deny yourselves of all ungodliness; and if ye shall deny yourselves of all ungodliness, and love God with all your might, mind and strength, then is his grace sufficient for you, that by his grace ye may be perfect in Christ; and if by the grace of God ye are perfect in Christ, ye can in nowise deny the power of God.
33 And again, if ye by the grace of God are perfect in Christ, and deny not his power, then are ye sanctified in Christ by the grace of God, through the shedding of the blood of Christ, which is in the covenant of the Father unto the remission of your sins, that ye become holy, without spot.
