Since there remains nothing for men, as to themselves, but to perish, being smitten by the just judgment of God, they are to be justified freely through his mercy; for Christ comes to the aid of this misery, and communicates himself to believers, so that they find in him alone all those things in which they are wanting. There is, perhaps, no passage in the whole Scripture which illustrates in a more striking manner the efficacy of his righteousness; for it shows that God’s mercy is the efficient cause, that Christ with his blood is the meritorious cause, that the formal or the instrumental cause is faith in the word, and that moreover, the final cause is the glory of the divine justice and goodness.

The Old Guys 
Amen! I am no longer condemned. Now, even when my heart condems me I know that God is greater than my heart. (1 John 3:19)
I received this grace of God through faith, and By this I may know that he abides in me and I in Him.
“When He shall come with trumpet sound, Oh may I then in Him be found.
Dressed in His righteousness alone, Faultless to stand before the throne.”
