The writer of Hebrews, having chastised us for being spiritually anemic and immature, begins the next chapter by saying we need to "Get on with it."  The word "therefore" says that he is concluding what he has just finished saying.

Heb. 6: 1-2  "Therefore, leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, Of the doctrine of baptisms and of laying on of hands, and the resurrection of the dead, and of eternal judgment.  And this will we do, if God permits."

All of the important beliefs that got you to where you are in Christ are laid out.

1.  Repentance.  You can't ever get started on a connection with God until you first are truly repentant. Not sorry.  Sorry doesn't change anything.  Repentance means you are guilty, and, not only ready to change, but ready to accept God's rules and authority.  Only Christ's perfect blood can cover our sin.

2.  Quit trying to get there on all the good things you have done.  God calls your good works, "Dead."  You can't ever do anything to undo the wrongs you have committed.  Our only hope is for Christ to step up at the judgement and stand between us and a death sentence.  He alone is worthy.  We aren't.

3.  Faith in God.  He is saying that faith is an obvious necessity for salvation.  You don't need to keep going back there.  You have it, or you don't.  Faith in God is a critical component of salvation.   No faith, no salvation.

4. Doctrines.  Of baptism, laying on of hands, resurrection of the dead and eternal judgment.  Arguments on the exact method of these subjects distracts.  Decide what God says on these subjects, but don't get stuck there.  Get moving forward to the meat of God's word.  Chew.
