Either believe it or stop saying it

I’ve been reflecting on baptism. When the officiant anoints the newly baptized and says, “you are sealed by the Holy Spirit in baptism and marked as Christ’s own forever,” do we really believe that? What if it’s the truth? What if our salvation has nothing to do with us; it doesn’t matter what we’ve prayed or not prayed; what we’ve read or not read; what we’ve done or not done? What if it’s just a matter of trust? What if someone did the trusting for us? Can you imagine? What if we could stop worrying about our eternal destiny and just live? What if living was more important than what happens later? Does that make God too good? Or does it make us not good enough?
