"The sacrifice of Christ makes those who draw near to God perfect" (Hebrews 10:1).
The Law made nothing perfect but Christ does!
"By one offering Jesus has perfected forever those who are made holy" (Hebrews 10:14).
"The spirits of righteous men have been made perfect" (Hebrews 12:22-23).
Another accurate translation of the word "perfect" is "complete." The word "saved" can be translated as "made whole." Thus when you are saved you are complete, you are made whole, you are perfect forever. "The Lord's work is perfect" (Deuteronomy 32:4). You are His work (Ephesians 2:10).
"The blood of Christ can purify our consciousness of dead works so we can worship the living God" (Hebrews 9:14).
"God is able to make His worshipers perfect in their consciousness" (Hebrews 9:9).
"The sacrifice of Christ has purified us one time for all time thus our consciousness of sin & feelings of guilt can disappear forever" (Hebrews 10:2).
"Our evil consciences have been removed by the sprinkling of Christ’s blood. We are clean. Let us draw near to Him with true hearts that are fully confident by trusting in Him" (Hebrews 10:22).
"A clear conscience depends on our knowledge of God’s grace & love for us, not on our own fleshly wisdom. It brings pure motives and godly sincerity to all of our behavior" (2 Corinthians 1:12).
"Your beauty is perfect because of My splendor which I bestowed on you,” declares the Lord God (Ezekiel 16:14).
These are Jesus' words to the parts of His body which is His bride, the Assembly, "You are so beautiful, my beloved, so perfect in every part." (Song of Songs 4:7)
Here is a song I made in 2007 with the same title as this post.
