You can’t describe the function of light only by what is lit but by shadow as well. Hebrews, for example displays the full light of Christ by describing not only his grace but his judgment of those who reject that grace.
By all means, rejoice in the great grace of Christ, by which men are forgiven and cleansed from their sins...but warn those who persist in error of the consequences. We say we follow the example of Christ who meekly gave himself up to be sacrificed for us. Yet this same Christ took whips to the thieves who profaned his Father’s house...( in his great love he only hit them he didn’t kill them) Should we not at times speak boldly with anguished righteous anger against those who corrupt our children, would profane marriage and the notion of Godly families, and would demand that we worship what is created and not the Creator? Are there not times that we should “sell our cloaks and buy a sword”...even if such a sword is no more than civil disobedience, like the Hebrew midwives who, fearing God, refused to obey Pharoah’s edict to kill the first born Hebrew males at birth?
I was where you are, not all that long ago.
What made the difference was personal encounters with the Holy Spirit. I had, like a whole lot of evangelicals, been trying to figure out, by the balance of gloomy and happy words in the bible, what God was about. And I was coming up with a confused, critical fog.
Once the Holy Spirit told me from the Father that I was indeed His son... bearing witness... the story began to fall into place. God has a STORY to tell, and CLAIMS to make. And the story is one of efforts to love a stubborn humanity, but also a humanity that has an eternal dimension, not just a temporal one. And the claims for those who believe are amazing.
I can’t stuff God down anybody’s throat, but I can make my sincere best effort to champion a saving gospel to him (or her).
One interesting thing to notice about all the events that occurred in Jesus’ life up to His sacrifice on the Cross... they were in the context of the OLD covenant. Not the new!
Incidentally Hebrews is mainly about chastisement in context for believers. It was an exhortation to Jews who had been saved but then were tempted to return to an Old Testament worship system. It does not posit loss of salvation, anywhere. It is about microcosms, not about eternity.
