"For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God." (Hebrews 7:19 KJV)
"Therefore, since we have been made right in God's sight by faith, we have peace with God because of what Jesus Christ out Lord has done for us. Because of our faith, Christ has brought us into this place of undeserved privilege where we now stand, and we confidently and joyfully look forward to sharing God's glory." (Romans 5:1-2 NLT)
Here is that simple thing to understand, which is so misunderstood: It was the sacrifice that Jesus made on the cross that canceled our debt! Yes, we had a very big debt, that none of us could ever never pay, no matter how many sacrifices we made or how hard we tried to work to keep the law; it was only by the blood of Christ, God's one and only Son, that we could be forgive for all our sins!
Now I know that there are some who can't comprehend how that works; but the simple truth of how it works, is the fact that the Father made it to work! He is the one who now sees us washed by the blood of His Son, and now we are perfect in His sight; plain and simple! The law was never canceled, and the promises have now been reinforced; all because of what Jesus Christ did on that cross.
Hopefully that clears up a few things about where we now stand with God, because we still face some trials over things we have previously done. But that doesn't take away from our relationship with God, or the fact that our sins have been removed. The things we did here on earth will stay here on this earth, but we arrive in God's presence perfectly clean and secure!
That is our great hope, which is based upon what God has done for us, not anything we have done for Him. We just need faith...
"Abraham never wavered in believing God's promise. In fact, his faith grew stronger, and in this he brought glory to God. He was fully convinced that God is able to do whatever he promises. And because of Abraham's faith, God counted him as righteous. And when God counted him as righteous, it wasn't just for Abraham's benefit. It was recorded for our benefit, too, assuring us that God will also count us as righteous if we believe in him, the one who raised Jesus our Lord from the dead. He was handed over to die because of our sins, and he was raised to life to make us right with God." (Romans 4:20-25)
