Hebrews 10 tells us that we should take full assurance of God's grace through faith in the blood of Jesus Christ.
Through the blood of Christ, we have confidence to enter the holy places. Though the old temples kept the high places behind the curtain with only the priest able to enter, Christ has opened the curtain for us through his flesh.
Since we have a great high priest over the house of God, we can draw near with a true heart in full assurance of faith. We enter holy and clean from all evil, as though our bodies were washed with pure water.
We should hold fast to this confession of hope. Never waver, those who are promised are faithful!
Paul said that we should consider ways to stir one another up, pushing others to love and good works. He said we should not neglect to meet together, though some people had already taken this habit in his day. We should encourage one another more and more the closer the Great Day draws near!
If we continue sinning deliberately after receiving the knowledge of the Truth, there is no longer a sacrifice for sin. Without faith, we fear a day of judgement with a fire that will consume all adversaries.
Paul said that anyone who aside the Law of Moses would die without mercy on the evidence of two or three witnesses. How much worse the wrath of God who profaned His blood, His new covenant that He Himself sanctified? If we do not have faith in Jesus Christ, we outrage the Spirit of Grace.
Therefore, remember the days when you first came to know Christ. You faced a hard struggle with suffering. You were publicly ridiculed and afflicted, sometimes along with others suffering the same trials. You had compassion on those who were still imprisoned, hanging onto the old laws. You joyfully accepted the plundering of your property, because you had a better possession awaiting!
Paul said do not give all of this up! Don't throw away your confidence when you have a great reward! Have endurance, so that you can receive what He promised after you have done the will of God!
As Christians, we should ask ourselves: Do we have assurance of our salvation by grace through faith in Jesus Christ? Do we enter the holy places with a pure heart, knowing His blood is sufficient? Do we stir others up, encouraging them to be excited for God and live by faith? Have we not remembered the trials we faced when we came to know Christ?
Don't give all of this up! Have faith!
