I used to think (and still do) that it was a cop-out statement when a Christian friend told me that instead of putting our faith in people, because it inevitably led to disappointment, we should put our faith in God. I mean, who else do we have apart from the people around us?
However, for me, the caveat is that the trust needs to be earned. Nevertheless, most importantly I think it’s necessary to back yourself in your own convictions, rather than depending on opinions or assistance from others. After all, you alone have the most stake in how you turn out, no?
