I believe depth does matter. It's called maturity, which comes through living a disciplined Christian life.
However, this relates to effectiveness, not to one's salvation. The ground which the seed is planted in may produce 30, 60, or 100 fold, but nonetheless, it's still called good ground. This is why we are told not to compare ourselves among ourselves. Instead we are simply to lovingly supply the support others need to live out their faith.
Even the mature have a fluctuating
state. Thankfully this doesn't affect our
standing with God. There are days when I am more disciplined than others.
On disciplined days I don't post on AFF!
