Hebrews 13  As the writer concludes this letter.. "this word of exhortation" .. he reminds us that walking in faith includes such things as:

loving each other
showing hospitality
having compassion on those in prison for their faith
honoring our marriages
being content with what we have;
Imitating  the faith of those who have led us to the Word of God.
and staying away from strange teachings.

God is our helper and has promised to never leave or forsake us.
Christ is our Savior who will never change!

So let us walk in faith.. believing..
".. it is good for the heart to be strengthened by grace.. "  It is God, Himself, who strengthens and establishes us in faith.. We come to Him, through Jesus Christ.. "outside the camp".  Not through the Law, through the temple, or through our religious rituals.. but by grace through faith.

Therefore we give thanks and praise.. We do good and share.. "for with such sacrifices God is pleased. " 
Like the apostles and writer, let us "have a good conscience, desiring to conduct ourselves honorably."  

" Now the God of peace, who brought up from the dead the great Shepherd of the sheep through the blood of the eternal covenant, even Jesus our Lord, equip you in every good thing to do His will, working in us that which is pleasing in His sight, through Jesus Christ, to whom be the glory forever and ever, Amen."
