Hebrews Chapter 11 speaks of heroes of the faith
"And what more shall I say? For time would fail me to tell of Gideon, Barak, Samson, Jephthah, of David and Samuel and the prophets - who through faith conquered kingdoms, enforced justice, obtained promises, stopped the mouths of lions, quenched the power of fire, escaped the edge of the sword, were made strong out of weakness, became mighty in war, put foreign armies to flight. Women received back their dead by resurrection. Some were tortured, refusing to accept release, so that they might rise again to a better life. Others suffered mocking and flogging, and even chains and imprisonment. They were stoned, they were sawn in two, they were killed with the sword. They went about in skins of sheep and goats, destitute, afflicted, mistreated - of whom the world was not worthy -wandering about in deserts and mountains, and in dens and caves of the earth. And all these, though commended through their faith, did not receive what was promised, since God had provided something better for us, that apart from us they should not be made perfect." Hebrews 11:32-40 ESV
Then Hebrews chapter 12 speaks of 'The Hero' of the faith
"Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God. Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted." Hebrews 12:1-3 ESV
Jesus is the hero we look to. Our heart is renewed when we look to Him and His victory.
I sometimes look at the things that seem to hinder my walk of faith... money... health... time... and then think of this great cloud of witnesses whose lives are 'made perfect' by us. People who gave all before Messiah had come and others who gave all after He was raised.
I don't want to stand before God and give puny excuses while these great men and women stand watching. They gave all... Christ gave all... by grace I will give my all... not in effort but in believing and functioning like one who believes.
