To be clear, sin is no longer the defining aspect of our relationship with God—Christ is! Grace is! God did away with sin, yours and mine, by the sacrifice of His son. We have been brought into union with Him and nothing, NOTHING can separate us from Him ever again. He has already given us every good gift and perfect fullness in Christ. What’s left out of 'every' and 'fullness'? I can’t think of anything. God has made His home in you and in me, and He will never, NEVER withdraw Himself or forsake us. He has made us righteous royalty in His family—No kidding!—and even if our radiant robes should drag in the mud of this world, like the father of the prodigal, He will never lawyer-up and prosecute us for waywardness or distant country visitations.
Our Father tore up the records and every regulation. No debt remains. We cannot pay Him back, neither does He want it. That would be insulting to Him and the staggering display of His love and grace, which He still likes displaying. It’s His thing! Have you noticed? It’s the new covenant. (And, like the prodigal's dad, our Father asks no questions.) At the risk of adding to the story, the prodigal’s father threw a parade in front of the neighbors as if to say, “He’s MY son! He is for me, and I’ll give him all that I want no matter how scandalous it seems to you!”
