These 2 things are the basic of what our faith is, without these, we are still a great sinner without hope.
These two concepts relate very well to my life.
I was a great sinner before I got saved but even after being saved I still sin in some way every day. Jesus saved me from my sins when I asked for His forgiveness and He is faithful to forgive of my daily sins when I ask Him to.
“But we are all as an unclean thing,
And all our righteounesses are as filthy rags;
And we all do fade as a leaf;
And our iniquities, like the wind have taken us away.”
Isaish 64:6 (KJV)
We can only be seen as been righteous through Jesus Chirst because we are sinners by nature.
