Hebrews 6 New King James Version (NKJV)
The Peril of Not Progressing
6 Therefore, leaving the discussion of the elementary principles of Christ, let us go on to [a]perfection, not laying again the foundation of repentance from dead works and of faith toward God, 2 of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment. 3 And this [b]we will do if God permits.
4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, 5 and have tasted the good word of God and the powers of the age to come, 6 [c]if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame.
7 For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God; 8 but if it bears thorns and briers, it is rejected and near to being cursed, whose end is to be burned.
A Better Estimate
9 But, beloved, we are confident of better things concerning you, yes, things that accompany salvation, though we speak in this manner. 10 For God is not unjust to forget your work and [d]labor of love which you have shown toward His name, in that you have ministered to the saints, and do minister. 11 And we desire that each one of you show the same diligence to the full assurance of hope until the end, 12 that you do not become [e]sluggish, but imitate those who through faith and patience inherit the promises.
God’s Infallible Purpose in Christ
13 For when God made a promise to Abraham, because He could swear by no one greater, He swore by Himself, 14 saying, “Surely blessing I will bless you, and multiplying I will multiply you.” 15 And so, after he had patiently endured, he obtained the promise. 16 For men indeed swear by the greater, and an oath for confirmation is for them an end of all dispute. 17 Thus God, determining to show more abundantly to the heirs of promise the [f]immutability of His counsel, [g]confirmed it by an oath, 18 that by two [h]immutable things, in which it is impossible for God to lie, we [i]might have strong consolation, who have fled for refuge to lay hold of the hope set before us.
19 This hope we have as an anchor of the soul, both sure and steadfast, and which enters the Presence behind the veil, 20 where the forerunner has entered for us, even Jesus, having become High Priest forever according to the order of Melchizedek.
Hebrews 6 New International Version (NIV)
6 Therefore let us move beyond the elementary teachings about Christ and be taken forward to maturity, not laying again the foundation of repentance from acts that lead to death,[a] and of faith in God, 2 instruction about cleansing rites,[b] the laying on of hands, the resurrection of the dead, and eternal judgment. 3 And God permitting, we will do so.
4 It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, 5 who have tasted the goodness of the word of God and the powers of the coming age 6 and who have fallen[c] away, to be brought back to repentance. To their loss they are crucifying the Son of God all over again and subjecting him to public disgrace. 7 Land that drinks in the rain often falling on it and that produces a crop useful to those for whom it is farmed receives the blessing of God. 8 But land that produces thorns and thistles is worthless and is in danger of being cursed. In the end it will be burned.
9 Even though we speak like this, dear friends, we are convinced of better things in your case—the things that have to do with salvation. 10 God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them. 11 We want each of you to show this same diligence to the very end, so that what you hope for may be fully realized. 12 We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised.
The Certainty of God’s Promise
13 When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, 14 saying, “I will surely bless you and give you many descendants.”[d] 15 And so after waiting patiently, Abraham received what was promised.
16 People swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument. 17 Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. 18 God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope set before us may be greatly encouraged. 19 We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain, 20 where our forerunner, Jesus, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.
