Its important to have the correct viewpoint of what perfection really is. A common error when stating what perfection is, is that many feel or think that perfection means being perfect in an absolute sense, that is, to an infinite degree, without limitation.
Perfection in this absolute sense distinguishes ONLY the Creator, Jehovah God. Because of this Jesus could say of his heavenly Father: "Nobody is good, except one, God (Mark 10:18). The Creator, God, is incomparable in His excellence, worthy of all praise, supreme in his excellence, supreme in His qualities and power, so that "His name alone is unreachably high" (Psalms 148:1-13, Job 37:23-24). All of God's ways, words, and law are perfect, refined, free from flaw or defect (Psalms 19:7, James 1:17). Other perfection is relative. Perfection of any other person or thing, then, is RELATIVE, not absolute. That is, a thing is "perfect" according to, the purpose and evaluation for which it is appointed by the designer or producer. The very meaning of the perfection requires that there be someone who decides when completion or relative perfection has been reached, what standards of excellence are, what requirements are to be satisfied, and what details are essential. Ultimately, God the Creator is the final Arbiter of perfection, the Standard-Setter, in accord with his own righteous purposes and interests (Romans 12:2)
Mankind's return to perfection on earth will come. According to the prayer "Let your will take place, as in heaven, also upon earth", this planet is due to experience the full force and effect of the fulfilling of God's original purpose for obedient mankind and the earth (Matthew 6:9-10). The wicked system under Satan's control will be destroyed.
At Matthew 5:48, Jesus admonished his disciples or followers to "be perfect (or faultless), as your heavenly Father is perfect" What did this mean? Jesus was say that his followers needed to serve and worship God to the very best of their ability, to walk with integrity according to God's standards of spiritual and moral excellence, as well as soundness of mind.....(Psalms 84:11, Psalms 26:1). So lovingly God allows us to worship Him despite us being imperfect as long as we keep doing our best to keep His commandments and love Him.
Adam and Eve were perfect, and yet they failed miserably in demonstrating love for their Creator and God. They disobeyed and lost out on everlasting life on a beautiful paradise earth.
