Suffering means growing up in the faith; sacrifice means giving up what is inefficient in the process (even the body, for example).

Growing up in the faith is what protects us … and so the soul needs to be exposed to temptation and suffering like the body needs to be exposed to viruses and bacteria to stimulate it to build up the anti-bodies so that it can grow healthy and resistant to disease.

But this analogy only goes so far. The body is inevitably corruptible and corrupted, what is not corruptible is the living hope of our unfading inheritance in heaven, protected by faith, the salvation prepared for us when the time is right.

Therefore, protect your inheritance, suffer as a Christian, grow in the faith, sacrifice what is necessary to grow in the faith.
