I read an article that got "the gears of my mind” turning. It mentioned putting "faith in the blood of Jesus," a phrase loosely based on Romans 3:25. (It never ceases to amaze me how I can read a particular scripture, any scripture, over and over again, and yet in a split moment have a lightbulb turn on that never turned on before.)
We all know we should put faith in God and in Jesus. But how in the world do we put faith in the BLOOD of Jesus? That phrase seems to carry a significantly different meaning. So I began to reflect if there was ever a time before where people had to put (or demonstrate) faith in the value of blood. As I researched different websites, one in particular extended the phrase "put faith in the blood of Jesus" to include the words "through actions." Then the lightbulb turned on. The Israelites preparing to exit Egypt were told to splatter blood on their doorposts. Those that put faith in that instruction and acted on it, were spared the life of their firstborn. Those that did not obey lost the life of their firstborn.
For the early Christian congregations, who were predominantly offspring of Abraham, they were under command to remember their deliverance from Egypt in a commemoration known as the Passover. For them to accept that "The Law" (handed down from God through Moses) and related Jewish customs were no longer needed, was a huge issue. Yet Paul mentioned that it was a necessary transformation. At Galatians 3:13 Paul reasons that we must now put faith in Christ, that is, that Christ purchased us (through his sacrificial blood) and thus released Christian converts "from the curse of the Law."
But faith in the blood of Jesus goes beyond removal of a curse. It was a huge breath of fresh air, a "new covenant," just as prophesied at Jer 31:31-34. This will help obedient ones appreciate that true loyalty to God goes beyond perfunctory observations of rituals. It is something deep in the heart of a sincere person. It is no longer "I'm required to obey," but rather "I desire to, I want to obey." God becomes more than some unseen, distant entity. He now becomes "Abba, Father." Romans 8:15-17
So for the early converts to Christianity, putting faith in the blood of Jesus (at least in part) came down to accepting that works of the Mosaic Law would not win them approval with our Creator. Back then, as well as today, trust that his Son, Jesus Christ, provides the ransom and the scriptural instruction we need to live a truly godly life is what is paramount for all to realize.
(I do not intend this essay to be an exhaustive consideration of the meaning of our putting “faith in the blood of Jesus.” The intent here was to provide a snippet of thought in appreciation that putting faith in anything requires demonstrable action.)
