Jesus is our example of perfection. Perfect in His lifestyle because He was tempted but never sinned. Perfect in His love for us even unto death on the cross. Perfect in His unity with the Father and the Spirit.
God, for whom and through whom everything was made, chose to bring many children into glory. And it was only right that he should make Jesus, through his suffering, a perfect leader, fit to bring them into their salvation.-Hebrews 2:10
When we talk about perfection, we are really talking about maturing spiritually. Jesus was, is and always will be the only perfect person. When God talks about perfection, He is looking at us through the perfect blood of Jesus.
20 Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, 21 Make you perfect in every good work to do his will, working in you that which is well pleasing in his sight, through Jesus Christ; to whom be glory for ever and ever. Amen.–Hebrews 13:20,21 (KJV)
Again, we see that “we” can’t do it, “we” can’t save ourselves, “we” can’t sanctify ourselves. “we” can’t make ourselves holy and “we” can’t perfect ourselves.. But with one act of perfect sacrifice, Jesus did all that for us.
14 With one sacrifice Christ made his people perfect forever. They are the ones who are being made holy.–Hebrews 10:14 (ERV)
God in us is perfecting us daily, so that we will be prepared for the glory that is heaven.
