We are those who are "perfected forever." However, "perfected forever" does not mean we are morally perfected. Rather, His one sacrifice is perfectly adequate to assure our standing before God. As we have seen, the sacrifices show Him proclaiming how He lived His life, but here we are seeing its impact, the consequences of what He did so well. We see man, sinning and imperfect, becoming at one with God through Christ.
By means of the burnt, meal, peace, sin, and trespass offerings, we see all of God's holy requirements met in Christ so that we might be quickened by His Holy Spirit, be in continual fellowship with Them, and grow to become fully at one with Them. Ephesians 1:3-6 adds Paul's thoughts on this:
Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, just as He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love, having predestined us to adoption as sons by Jesus Christ to Himself, according to the good pleasure of His will, to the praise of the glory of His grace, by which He made us accepted in the Beloved.
The consequences of Christ's sacrifices do not end with our acceptance before God. Acceptance creates the requirement of being conformed to the image of the Son; we are expected to walk in newness of life (Romans 6:4). Peter frames his instruction on our responsibility once we accept Christ's sacrifice in our stead in this way: "Coming to Him as to a living stone, rejected indeed by men, but chosen by God and precious, you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ" (I Peter 2:4-5).
This is in language any of God's children can understand. We are to offer up sacrifices in the way He did. There is not one record of Him ever making a sacrifice at the Temple. Rather, He lived their intent as a living sacrifice. This is why our identification with Him is so important. We are now part of His body; we represent Him. He lives in us, and we experience life with Him as part of us. Our conduct is open to the view of all who care to look. Are we glorifying Him?
Please understand that, though our offerings will be poor and weak in comparison to His, they are not worthless by any means. They are still acceptable to God because of Christ, and they are still a witness.
Consider these illustrations: If a couple have a small child of perhaps just a few years of age, do they expect him to run one hundred yards in nine seconds? Are they disappointed because he cannot drive a car or understand Einstein's theory of relativity? Of course not! If their child is only one year old, he may just barely be able to toddle across a room! If he falls a couple of times, do they lose their temper and put him out of the house?
Of course, they are neither disappointed at his present inabilities nor do they even think of putting him out of the house. Why? Because they know he is just a baby, and they adjust their expectations and judgments accordingly. They are confident he will get better as he matures and gains experience. They know that someday he will stride confidently across the room and much more besides. Someday, he may run a hundred yards in under ten seconds and grasp the essentials of the theory of relativity.
In other words, growth is anticipated. God's judgment of us is much the same. When we are first in Christ, He considers us as babes (I Peter 2:2; Hebrews 5:13). At this point, He very well may consider us as "perfect" for the time since our regeneration, and we are acceptable because of Jesus Christ. He allows us time to grow, even though we may make mistake after mistake because of our weakness and immaturity. Because of Christ, He keeps judging us as "perfect."
This is a wonderful gift! He is not overly concerned about our individual sins as long as He sees in us a steady, upward trajectory toward maturity in our conduct to reach the measure of the stature of the fullness of Christ. If a child falls as he toddles across the floor, will not his parents set him upright, dust him off, comfort him, and show him, "This is the way you do it"? Can we expect any less from God, in whose image we are? Therefore, our acceptance before Him gives us time to grow.
