Been thinking about identity and who we are as individual people. Much like the old adage about never stepping in the same river twice, we are not the same person we were yesterday and we are not the same person we were when we were younger. We are different mentally, physically, and spiritually.
The only thing that connects with who we were yesterday is the memory of it. But how does salvation relate to this - I've heard so many people that your salvation is secured and that you don't need to worry about it. I like the Catholic understanding of salvation. That we are saved, that we continue to be saved and that we will be saved.
The moment of our salvation becomes a memory - a moment in our past. And each day we can choose to make that moment our most significant. It influences the choices we make, and informs who we are on this day. Each day we have the opportunity to choose to be identified either by our past successes or our past failures. We have the opportunity to be defined by our salvation or our past brokenness.
It does also means that we can leave our sin behind, we don't need to carry it in to the next day. It was who we were but not who we are.
